Run the gauntlet

An extreme internet challenge, where you are tasked with watching some of the most horrible videos out there. There are 20 levels and each one gets harder. They include a dog being skinned alive, a baby being run over by a car, and the infamous "three guys one hammer". It is currently unknown why anyone would do this to themselves.

When you risk running errands or driving to work when you have no registration and a suspended drivers licence.

Variant spelling of "run the gantlet." Spelled either way, it's pronounced gauntlet. A gantlet is a double line of people with clubs, whips, tomahawks, fraternity paddles, or other weapons; the poor bastard being punished runs between the lines and everyone hits him as he goes by. Depending on weapons and circumstances, this has been used as an initiation, a test of courage, a way to decide which prisoner to let go (to take the message back that you are holding hostages), or a way to execute someone without making any one person responsible. Often used to describe what the in-crowd does to a noob before accepting him -- "Making him run the gantlet" is a stronger, more violent expression than "making him pay some dues" or "putting him through all the hoops."

To expose oneself to danger or the criticism of others.

When you and your mates go to stop by every pub, party, club, so on... in one night while drunk of your head.

having unprotected sex with a particularly skanky slut you just picked up on a night out, and praying you don't catch any STD's (sexually transmitted diseases) from her.
