Basically when something is really funny but it’s not funny enough for”JSBDJSNWJ” kind of language so you use SKSKSK it’s almost like LMAOO
Or
When you are hella confused or
disappointed in someone so you say SKSKSK insert
person name
Person 1:Omg sis did you hear that
Rebecca failed math and has to stay behind
Person 2: OMFG SKSKSKS😂
Or
P1:gurl omg I just got a huge hickey
P2: OMG GURL SKSKSKS WTF
