1. Getting dunked on (getting spiked)
2. Getting overwhelmed
In the game Super Smash Brothers for the Wii U and 3DS, there was a tournament called SCR Saga, and that tournament was sponsored by Gushers. So that made Trela use the term "Gushed" when someone got spiked or got overwhelmed.
The act of sticking Gushers into your partner's anus, having them clench hard enough to burst the gushers open, then sucking the gusher goo from their cornhole
Amanda: "Justin gave me a Gusher Crusher last night. I gotta say, it was pretty fun"
Laurel: "I just love giving my boyfriend Gusher Crusher's, Watermelon blast is my favourite!"
