The additional piss that falls from your dick when forgetting to shake it off, which usually drips onto the pants of the victim leaving a stain looking like your pecker just druled and for everyone at the party to humiliate you.
"SHIT! i got some pecker drule on my jeans, i guess i'll just wait in the bathroom until that shit dries up, wheres my natty light."

Victim-"Yoo look, i got some pecker drule on my jeans... pleassse don't tell anyone man, that shit is embarrassing!"

Friend-"Heyyyy everyone, look, this little bitch over here forgot to shake his dick( 3 times only, any more shakes and your beating off) and got pecker drule all over himself."

Victim-"You asshole"
