Derived from an advertisement for Orange in the United Kingdom, 'I just bought broccoli, lol!' is a deliberate satire on when people write stupid, unnecessary things as their Facebook status or Twitter tweet. Can be shortened to IJBBLOL.
Random blonde facebook chick: 'Hai gais, jst kssin ma bf rite nao brb'
Person with more than half a braincell: I just bought broccoli lol!
Guy at uni for no other reason than to get stoned out of his mind: d00d. so hi rite nao.
Person with more than half a braincell: IJBBLOL!
A nicer way to say I don't give a shit on public forums where children go. It's ironic because the only reason to say this is if you actually give a shit about who reads it.
Person #1: Did you know that Justin Beiber was here yesterday?!?! :D
Person #2: Seriously, I don't give a lol.
This is a phrase used in counter-strike or any type of PvP / FPS / RTS game. It is used to taunt your opponent when you have either landed an amazing head shot, double kill, or completely owned a bunch of noobs.
Term came to light on the well known tube video 'mad cause im stylin', where a rap battle took place and the guy who used the line got socked in the face.
Basically, it is used to anger your opponent and declare your dominance.
Noob: You, you're a hacker!
Noob: OMG HOW DID YOU GET ME THROUGH THE WALL LIKE THAT!!
Random guy: RAINDROPS!!!!
You: lol you mad cause I'm stylin on you??
