RUFS is
short for "R U Fuckin
Serious?!" Used for those occasions when "are you
serious" is just not enough to question the seriousness of a situation.
For use as an exlamatory phrase, 'I was about to go dick deep in this bitch in the bathroom at da club until she opened her
legs and it smelled like week old fish in a
dumpster in the 100 degree
sun and i was all like RUFS?!"
