Gargantuan Blockades 

Gargantuan Blockades is a Mega Walls sweat clan. Unlike the other stupid fucking clans on Hypixel, Gargantuan Blockades is not a cheating guild. Some cheating guilds are known as Hood and The Jungle. The clan is lead by Turblue, a bitch who eats cock. Whenever they win a game after losing ten times in a row, they always say “L KID #THEGUNGA” at the end of the game, stating that they’re better than everyone else.

Person 1: These guys are saying “L KID #THEGUNGA”!
Person 2: That’s Gargantuan Blockades, no one knows who they are lol
