Mine: "Parm" for parmigiana, "veg" for vegetables, "sammy" for sandwich (this was
, of course, a discussion born out of a food thread...that doesn't need to limit the discussion now, though). Oh, and "tho" for though.
Oddly, I love "sammitch/sammich" but hate "sammy."
I will leave out the IM-speak, as it's pretty much uniformly irritating.
ps Sorry cubanat, I know you just came back from vacation, but this may be like fingernails on a chalkboard
