SNS 

SNS = South nigga shit.
Basically, when somebody is doing something bizarre and/or stupid, it's safe to assume he's either from the south or has been heavily influenced by the region.

When you see a guy pondering the age old question, "what's 13-50?". That's just SNS.
When you see a guy on a date with his cousin. That's just SNS.
When you see a guy feeding a raccoon. Best believe that's some SNS.

SnS 

"Smoke 'n' Shit." Used when describing a break during work, where you go for a quick cigarette and a shit (not necessarily at the same time).

Employer: "I need you to finish that report."

Employee: "I will, after a quick sns break."

Employer: "Oh shit, I'm jealous."
