A fictional medical doctor who smokes enormous amounts of marijuana (see def. of Jenkins) and frequently participates in stoner activities, including, but not limited to: disc golf, ultimate frisbee, hacky sack, hula hooping, devil sticks, juggling, hiking, bungee jumping, hang gliding, baking brownies. He also has a habit of prescribing Xanex to every one of his patients - which is amazing considering he's a chiropractor.

When you and your partner discuss at long the intentions of your sexual persuits right before you make love. Then at the last second the male abandons all this and screams, "Leeroy Jenkins!" and just penetrates and goes to town.

Leeroy Jenkins is defined as a soldier or person to engage in a conflict so as to inspire his fellow soldiers or friends to join in the fray regardless of circumstances or odds of survival.

The term is derived from a legendary soldier in the online PC game World Of Warcraft in which Leeroy Jenkins interrupts his comrades during a moment of strategizing on the outset of an imminent battle to which their odds of survival are 32.33% and screams his now famous battle cry, "LEEEEEEERRRROOOYYY JENKINS!" and charges into enemy territory. Leeroy's spontaneous outburst and act of bravery shocks and inspires his fellow soldiers and they too charge after Leeroy. The battle ultimately ends in a decisive defeat leaving no survivers thus immortalizing Leeroy Jenkins as the embodiment of bravery and sacrifice.

The courageous act was recorded and posted on youtube in 2006. just type Leeroy Jenkins into the search field.

The event has been referenced on many flatforms and mediums such as the popular television show Final Jeopardy and also on The Howard Stern Show.

Either the bravest SOB in World of Warcraft history, or the stupidest; depending on your point of view. Rushed into an enemy stronghold alone, roaring his name; forcing the rest of his guild to follow and turning their chances of victory from 32.33(repeating)% to zero. At least he has chicken.

To "pull a Leeroy Jenkins" is to rush into a dangerous situation alone without following strategy, forcing your allies to follow and leading to the inevitable, definitive, graphic demise of your team. In essence, your entire team got wombo comboed because of you. If you don't try to laugh this off by saying, "At least I have chicken", or at the very least acknowledge your foolishness, you not only fail at the game, you fail at life.
Note: NEVER try to pull a Leeroy Jenkins if you're an actual member of the military. Chances are no one will make it out alive. And you won't even have chicken to comfort you.
