This annoying habit seems to be more prevalent in the restricted-vocabulary circles, so I suppose this is their only way of standing out in a crowd (yes, this is a snooty post).
My gripe this time is people who add consonants in an attempt to add emphasis (I’m assuming that because they don’t have a very wide vocabulary, alternate word-choice is not an option, but that may well be presumptuous on my part).
Examples would be: Hott, Starr, Raddical, Sexxy, Dogg, Rockking
