SMP - Suck my P****. Nah, just kidding. It's "Survival Multiplayer", like survival mode in multiplayer..

Also,SMP is the short form of SIMP

Someone who is possessed by clout chasing. The original human is now gone and a demonic entity that feeds on clout is all that is left. An empty shell with no control of their actions, forced to blindly react to situations they think will bring them attention.

It stands for "Survival Multiplayer". It's a Minecraft Survival world but in Multiplayer mode. There, you can mess around in your survival world with your friends.

Stands for "suck my pussy," derived from one of Sophitia's special grab move in Soul Calibur III, where she takes her opponent's head, puts it between her legs and jumps on the ground jamming her crotch in their face at high velocity. First stated by an intense brown gamer when he was losing in frustration to a stupid white guy, where he rejoiced "suck my pussy" when he won.

Now, SMP is used as the short form, synonymous to Feel It.

"Shit My Pants" It's a non-lame "lol". What's radder, laughting out loud, or shitting your pants while laughing? Ya.

S.M.P, the act or thought to smoke more pot

it means "suck my pussy" its like SMD but for girls :)
