A term used to describe the penis of a U.S. soldier returning from the Iraq war who is looking to get lucky.
Specificly when he lands a girl willing to go the distance it is thought that his initial penal engorgement will be a whopper, from a lack of sexual stimulation for long periods.
Also thought to be sex that is rough, greedy and slightly desperate in nature.
"Dude I got back from the sand box last night and tonight I already got lucky."
"All right battle buddy! Did ya' clobber her with your rape bat?"
"Yeah dude! Whiped out my rape bat and clobber f@(ked her!"
