The act of stretching your half erect penis as a handle bar moustache on someone, i.e.: your lover or friend, over their upper lip, and taking a picture with your phone then sending it to said person.
You may also show friends, if you manage to get away with this act.
"Dude, look at this!"
"Is that your dick?"
"Yep, I totally gave my girlfriend an Oklahoma Handle Bar last night."
