naked smack down

Naked smack down (noun-verb) usually occurs when one of the guys in your group decides to get completely naked when you and the fellas are together hanging out. Most times a slap will be thrown by the naked man at and/or towards a fully clothed member of the party. This prompts that member of the friend group to also get completely naked and so on and so forth. This practice is extremely dangerous and will usually result in many palm sized welts on your butt and back. Naked smack down are completely unannounced so always be on the look out for the most liable member of your friend group.

Terry: Hey what happened at Tommy’s the other night? I heard someone ended up in the hospital.

Larry: Yeah Brett decided to start naked smack down and Ray got caught in the eye by Harry’s testicles when he was trying to choke slam Dylan.

Terry: Gnarly! Ray’s wife is gonna be pissed!
