A penis fart is when you sleep with someone and you know it to be an absolutely horrible idea but yet you still hit that anyways.
'Man last night i had the biggest penis fart...... cant believe i did that to your sister'

'Dude, she made the titanic look small, that was such a penis fart'

'Why is it everytime I go to Mooseheads bar I wind up having a penis fart?'
