NSM is short for "nique sa mère" in french, which means "fuck his mother"
"putin nique ta mère (NSM)"
(Nsm) meaning - Not Saying Much
You could be in an argument with your girlfriend/boyfriend or wife/husband whichever and he/she we have caught you red-handed and brings up some evidence of some sort and then BOOM the βNSMβ ( not saying much) comes out!
I have NSM all over my Tinder so there is no confusion.
