Something that fails miserably
by AYB March 13, 2003

Flop-on is the term used when a male is unable to achieve an erection due to excessive alcohol consumption.
Did you hear what Hunter did it last night? He got totally wasted and attempted to fuck this amazingly hot girl but he got his Flop-on....again!
Awh man! I'm sorry. I've got my Flop-on. No action for you tonight.
