you know this fucker right here? in the old days it was just:
this fucker right here, is supposed to be a friendly and happy smiley..
but you know what...
i always seen it as the "sarcasm" or "troll" or "i am better than you"
if it was used by my crush: happy nice smiley
everyone else: this guy is making fun of me
for example
OP: well, i like cereal for my breakfast
person2: i preefer toast
you see right here!!! the person 2 is not using the smiley as a friendly smiley, but to tell op that his choice sucks, and basically saying "you are an idiot if you don't say toast"
or when your ex girfriend texts you
ex-gf: how had you been?
person: i am good, what's up
ex-gf: i seen you at the cinema
damn, that bitch, she used the smiley to express i shouldn't be at cinema or having fun, wtf she wants?
