SMFS

Suck my fuck stuck, a sudden outburst of frustration, also used to let someone know you will not do what they have asked of you. In a humorous situation it can be used to simply say no.

“I broke up with my girlfriend today cause I realized I wasn’t able to forgive her for sleeping with mom.”SMFS!

SMF

Usually used as a text abbreviation, (much like "SMD"- "Suck my dick"), SMF means Suck my farts.

"Hey man, you really suck, we can't hang out anymore."
"Whatever, SMF!"
