Dongers refers to the sexual act of putting your penis inside another mans asshole who then sticks his fingers in the vagina of at least four girls at once. This practice began in ancient Mesopotamia during 200 B.C. The Dongers position was left out of the Kama Sutra on account of being too lewd but was recently recovered in a undisturbed tomb. These days its very common for kids to "Dongers" and post the pictures to Vine as a form of social protest.
A catchphrase made by League of Legends player Michael Santana. The phrase is now spammed by his fans in livechats, after he first used it in a twitter post in June stating, ヽ༼ຈل͜ຈ༽ノ raise your dongers
