Form of revenge for such acts as the Mexican Avalanche or Strawberry Milkshake when during a perfectly good bj the chick bites into your rod and you burst a bloody wad, much like lava from a volcano
Dude, Im achin from that volcanic eruption last night.

this is when your girl ties your penis with a rope and then starts to give you head or a handjob. when your about to come, tell her and then she'll take out a knife and cut off your penis at the rope. the mix of blood and cum shooting out will be like a volcanic eruption.
david had to go to the ER after his girl gave him a volcanic eruption. he lost a lot of blood, but he should be fine.
