The incident happened whilst the president was visiting Irvine Valley College in Irvine, California on Friday to meet with older adults and tout his administration's efforts to reduce inflation and drive down costs.
As the visit came to an end, he stood to pose with some of those who had gathered to hear his remarks.
Aside from explaining how he might curb inflation and lower the cost of prescription drugs, the president also dished out dating advice.

'Now, a very important thing I told my daughters and granddaughters, no serious guys until you're 30!' he told one teen.
Biden stood to take a photograph with the girl and whilst doing so, he appeared to sniff the girl's hair before imparting the 'fatherly' relationship advice.
The girl appears to be genuinely uncomfortable and laughs nervously as she turns around to look at the commander-in-chief, who continues to rest his hands on her shoulder.
'I'll keep that in mind!' she responds while laughing it off.
The creepy moment was captured by reporter Kalen D'Almeida who then posted it to his Twitter account.
D'Almeida noted how a secret service agent appeared to try to stop him from filming as the awkward encounter took place.
In March, Biden also took it upon himself to give the exact same dating advice to a group of eight-year-old, third-grade schoolgirls, saying 'the only thing I want you girls to remember, no serious guys 'til you're 30 years old.'
Many Twitter users were deeply uncomfortable with the president's behaviour on Friday.
'What a creep. That poor girl doesn't want his repulsive hands on her, nor him breathing into her face. And what business is it of his as to who she dates and when? He's disgusting and inappropriate, among many other things,' tweeted Vanessa Peveto.
'Serious question… Why does he always do this? I can't tell you how many videos I've seen of him telling little girls stuff like, 'Remember, no dating until you're older', etc... It's just flat out weird,' declared another user.
'He has no concept of social cues. Look at the body language, the way she pulls back as she's clearly uncomfortable all the while he leans in further. Inappropriate. Creepy,' explained one Twitter follower.
'Why the hell can't he keep his hands and thoughts to himself around girls and young women- haven't his handlers talked to him in depth about this?' wrote another angrily.
The creepy antics are the latest to occur in Biden's 50 years in politics.
People took to Twitter to express their thoughts on the situation

Biden has a history of making eyebrow-raising remarks about girls and women.
In May 2020, Bidengave his teen granddaughter a kiss on the lips while giving a speech at a campaign trail event ahead of the Iowa caucuses.
The former Vice President was spotted clutching then 19-year-old Finnegan Biden's hand as they arrived at a campaign event at Clarke University in Dubuque, Iowa on Sunday.
The following year, in May 2021, Biden was slammed for 'creepy' remarks he made about a young girl during a speech at a Virginia military base.
On that occasion he went off-script to point out an 'elementary school-aged' girl as he delivered an address at Joint Base Langley-Eustis.
'I love those barrettes in your hair, man' the President said to the girl, who was sitting at the side of the stage
'I tell you what, look at her, she looks like she's 19 years old, sitting there like a little lady with her legs crossed' Biden bizarrely continued.
The girl's mother had reportedly introduced Biden to the stage prior to his speech.
Footage of Biden's odd remarks was shared to The Post Millennial's Twitter page, with many users perturbed by what they heard.
Last year, during an event in Florida, Biden told a group of underage female dancers 'I'm coming back and I want to see these beautiful young ladies, I want to see them dancing when they are four years older too!'
In 2019, he told a 10-year-old girl 'I'll bet you're as bright as you are good-looking.'
He has also been photographed over the years kissing and touching young girls and women during public events.
During his presidential campaign, three women also came forward accusing him of acting inappropriately.
Biden responded with a public statement, saying 'In my many years on the campaign trail and in public life, I have offered countless handshakes, hugs, expressions of affection, support and comfort.
'And not once, never, did I believe I acted inappropriately. If it is suggested I did so, I will listen respectfully. But it was never my intention.'
Former Senate staffer Tara Reade has also accused the President of assaulting her while she worked for him back in 1993.
He has vigorously denied the allegation on multiple occasions.
