origin: a long time ago (a couple years back), the most famous wow player leeroy jenkins went with a raid with a couple other people. he was away from his keyboard and was missing out on the battle plan. while they were discussing it leeroy jumped on his computer and said "lets do this" and yelled out "LEEEERRROOOOOY JEENNNNKIINNS" everyone was shocked when he ran through. in short he got his whole team killed.

1.to do something rash and extremely stupid usualy in a group.
2. to do something rash but brave.
1. that idiot went and got his whole team killed, i wish he hadn't leeroy'd it.

Started a online fad of epic proportions. Just when you thought Numa Numa Dance was big, a World of Warcraft guild makes a video *staged or not dosent matter* that made everyone laugh. The video has a group
raiding some place and the guild is planing raid this one room that gave them probs in the past. As the raid is about to start a player in the group by the name "Leeroy" jumps up says his name and causes tons of monsters to kill his group. After everyone is dead and everyone is pissed at Leeroy he respons with the epic words "Atlest I have chicken."

Leeroy Jinkins in doing so became a internet star, but at the cost of never being able to play as Jeeroy again, being people will flood him with PM's and mail.
Leeroy-"Alright chums lets do this!

Other player-"Oh my god he just ran in..."

*later on*

Some player-"Leeroy you're just stupid as hell..."

Leeroy-"Atlest I have chicken."
