they generally fall into one of two categories:
1. prudish sXe- these are the non-violent ones that are content to feel self-righteous about upholding a christian lifestyle (even though sXe is "not" christian).
2. nazi sXe- the ones that kick people's asses because they do drugs. yeah that makes sense, personal freedom is a bad thing, but beating the shit out of people who disagree with your set of ideals is just great.
However, it CAN be used as "sexy", or can be a misspelling of "sex".
Guy: Carmen...Yeah, she's fuckin' sxe.
Other Guy: Yeah I know, she turns down drugs/beer/casual sex when offered. I know...'cause I already asked.
Guy: Dumbass, I'm meant sexy.
Other Guy: Oh, my bad, thought you were talking about straight edge (FTW).
Guy: Fuck the what? Nobody cares about that trend.
Other Guy: No, I meant the lifetime commitment, non-fad kind.
Guy: Oh, that's fuckin' alright, then.
Straight Edge: "Ahem *makes a big scene* NO!! I'm Straight Edge!duuuhhhh I dont drink!"..
Here is that example again in normal curcumstances..
Person 1:"Would you like a drink"
Person 2: "No, thank you"
Rich: "you retard, you saying your straight edge is like me saying im an anarchist, all because of some trendy ass song..."
