gibgasm 

When you react in a way that wasn't intended. Almost like you lost control of your body. Examples: 1. When you're holding a random object and for no reason at all you throw the object. 2. When in a conversation you get overly excited or angry without realizing it or being able to control it.

I was holding my phone and had a gibgasm and hit myself in the face with it.
I had a gibgasm holding a glass of water and threw it across the room.

Person 1: We have to go to the grocery store.
Person 2: I HAVEN'T LEFT THE HOUSE IN DAYS! I CAN'T WAIT!
Person 1: Don't have a gibgasm... It's just the grocery store.
