a not well known term to describe a very attractive man capable of pulling any woman they want. they're very charismatic and are similar to the character stefan salvatore from the vampire diaries.
"oh my god.. that man is a stefussy! i'vealready fallen in love with him"
this phrase is actually an acronym. its a combined acronym with another at the end. such as "rofl". people then started adding copter at the end. "soul" is added to the acronym "stfu". its origin came from a boy named Soul`1k on counter-strike. people didn't really like him so they all just said stfu soul. so now people commonly use it to make fool of someone when they are talking
Kelvin: hey, so did i tell you
Arnold: No you didn't now stfu soul.
Kelvin: LOL WTF
