When fucking your partner and they call out the wrong name in bed. You then pull out a taser, cattle prod, stinging nettle, anything that is to hand, and attack them with it. Typically on the backside, but testicles or nipples work best.
Emma: hey how’re things with you and Simon?

Andy: not great.. he called out his ex’s name, Kieran, in bed last night so I had no choice but to furious jellyfish him.

Emma: oh that sucks. Let’s bone.
