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?!"
Rusman a name that looks wierd and familiar at the same time, he's most likely to be found in a room that is dark and gloomy but inside he's a verry bright and lovable person, he might not look like it but he's a teddy bearon the inside.
