Going Full Tank

When a parent has NO clue when kids talk to them in gamer language

Husband and I sitting on couch listening to our kids talking to each other over gamer headphones and one says to the other that they should go full tank. Husband and I looked at each other and started laughing and decided that "going full tank" should stand for gamer talk that parents dont understand

Babe, Our son was talking to me about League of Legends and I had no idea what he was talking about. He was going full tank.
