Big, blue bastards from Half-Life. They shoot flames from their arms and can stomp on the ground, sending some sort of red energy at you that can do considerable damage. Some have said that the gargantua cannot be killed with weapons. Do not believe this, because they can be killed, by using explosives or energy based weapons only. It's better to find another way to kill them, as they take quite some punishment before going down. They are rarely found in the game. They are not synthetic or machines of any kind. Sven Co-op has a smaller version of this creature, the Baby Gargantua.
As Gordon ran into the power room, the gargantua began to chase him. He could've used his grenades, but he didn't want to waste all 10 of them. Instead, he led him to the power room and switched on the power. he watched in satisfaction as the gargantua was fried by electricity.

1. A whore that is larger than life. He/She maintains a level of whoreness beyond any normal whore.

2. A fat lard that lays in bed all day and whores out. Can also pertain to obese people who give out sex like candy.

3. In prehistoric times, a Gargantua-Whore would rome the land searching for sex and cause mild earthquakes along the way. If one was to cross its path, they would have to fuck their way for freedom or pay the mighty price of being keestered. The keestering would last for weeks and if you survived or escaped, then you would smell like ass for all eternity.
"Jimmy sure loves those Gargantua-Whores. I walked into the kitchen this morning to find one of his girls eating breakfast. She was so huge, her cereal bowl came with a lifeguard."
