When you hook up with a girl that has a mustache, and cum on her uppper lip. Then grab a Bicrazor and shave her mustache using the cum as shaving cream.
I took this girl home last night, and she was in need of a shave. After a blow job, I came on her upper lip and broke out my razor to perform a Bic Dick.
A method of riding dick which is similar to the motion of riding a bicycle, where the person riding uses their thighs to move themselves up and down and from side to side, just like riding a bicycle.
As enjoyable as this may be for the participants, it can sometimes leave the rider feeling sore in the genitalia region—also similar to the effects of riding a bicycle hard and fast.
As referenced in the Ariana Grandes song "Side to Side", in which guest star Nicki Minaj sings, "Wrist icicle, ride dick bicycle".
"I saw you leave with Sam last night. You two do the dirty, or what?"
"Oh yeah, I rode the dick bicycle marathon up until the break of dawn."
