SA? does it mean smart ass
If you are referring to the latin slang "essay" (not sure on the spelling) then the word means "cousin" in Spanish I believe. In what context did you hear this word?
If funguy's answer is not about a spanish cousin, SA stands for Sexual Assault.
but it also depends on how you use it. eg. he sa'd me. or eg. im 4rm sa
haha i would of thought it meant sex addict hmm maybe i was wrong
thats what it means were i come 4rm
LOL, I am going with South Africa!
