Get a juggernaut mug for your brother Abdul.
A supervillian of the marvel universe. His real name is Cain Marko. He got his power by touching the Crimson Gem of Cyttorak. True to his name, Juggernaut is a near unstopalbe force! Once he starts going nothing can stop his motion! Despite his association with the X-Men he is not a mutant, he is an avatar. In the x-men comics Juggernaut is the step brother of professor X, but the movie "X-Men the last stand" which features the character makes no refrence to this.

A sexual act where the female bends as far over as possible, grabbin' her ankles, and the male, with his erect genitalia, runs full force towards his mate and with perfect aim, inserts and screams, "I'm the Juggernaut bitch!"
"Dayum he gave her the Juggernaut!"
"Bend over baby and lets try the Juggernaut..."

A perk on Call of Duty 4: Modern Warfare that enables the user to incur extra damage without dying. Often used by the most homosexual of online gamers, Juggernaut users usually die after being shot 31 times, when most weapons only shoot 30 rounds.

Major enemy of: the headshot; the knife attack.

Major ally to: the noob tube; the random grenade.
Man one: I had that motherfucker dead but he's camping in corner with a SAW and Juggernaut.

Man two: What a dicklicker.
