A trollup is a slut but as everyone knows not all sluts look or come off as a slut , a girl can look very presentable and still end up being a slut which is a trollup.
A skank is a girl who just looks like a fucking whore and wears clothes to no clothing if any. But again not all skanky looking chicks are sluts , some are really prudes which sucks.
So when you see a skanky looking chick and she ends up being a trollup after all she is a fucking SKROLLUP
Dude, I overheard this skrollup the o ther day. She says to her friend, "So I woke up yesterday morning, surrounded by 12 dudes, ALL with their dicks out... and I just realized, I gave every single one of these dudes a rim job!! But no worries, I threw on my halter top and 4 inch heels, got the FUCK outta there!!!"
