The mayonnaise packet is a sexual activity in which someone cream-pies someone and then proceeds to ground-pound their abdomen causing the "mayonnaise" to come out of the packet.
I did the mayonnaise packet with my partner! It was a very intimate experience!
When a girl asks, during sex, to receive the man's load on her, after the man has (or is currently) cumming into a condom, but not wanting to disappoint, the man distracts the girl and squeezes the contents of the now soiled condom onto the girl.
"Dude.. i can't believe you gave her a mayonnaise-packeting last night!!!"
