lx
Pretty much the "fetch" in Mean Girls in replacement of "xo" or something else slightly more normal (despite however much cringe-worthy).

Basically what dweebs say because they're trying to make up a new abbreviation that will never be cool because,

a) They're the only ones saying it.
b) No one knows what it means.
"Ur shit
