What is Assembly-dick?
1.
The act of lining up multiple girls on their knees, running by with your big fucking dick hanging out, and hitting them all in the face. (Preferably at least 10 girls, and hot cum shooting from dick onto their faces.)
Dude, were you at that party last night?
Yeah, i was in the back with a couple chicks, you?
Aww man! I lined up like 15 crazy-drunk bitches and pulled an assembly-dick.
