Originally shorthand for "slick's in," later becoming more of a verb used as congratulations after an individual finesses themselves into or out of a sticky/tricky situation often used by skaters, surfers and other people who say "brah" or "bro" every sentence or so.
Bro 1: Check homie over there finessin' with Venessa, damn she fine!
Bro 2: Hell yeah, she a freak! Slixin son!
Bro 1: Bro I swear I was pushin' 60 in a 40 on the way to work the other day. Caught a cop creepin' up in the rear view and took a quick detour like skirrrrt before he had time to turn and flew through a back route, made it right on time.
Bro 2: Daaamn dogg, you know that mofo was itchin' for a ticket on that shit!
Bro 1: Yeah and I said "NOT TODAY BEEYOTCH hahaaa!"

Bro 2: Sheeiiit, straight slixin' mane!
