The act of repeatedly squishing (or squibbing) up and down.
The term was first coined by fans of Amaris Yuri, an english VTuber, and associated with a goofy-looking emote of the VTuber squishing up and down.
"someone being a bitch?
squibby on them.
someone threatening you and your family?
squibby on them.
family member died?
squibby on them.
dont care didnt ask?
squibby on them.
love them?
squibby on them.
hate them?
squibby on them."
-Amaris Yuri
When a couple does anal for so long, the dick starts to push in there stomach. The acid from the stomach starts to corrode the dick. Since there dick is in the liquid acid the dick starts to get very soggy, and falls off as well being dissolved in the stomach. The dick is now a small little stub that looks like an erect clit, with balls, that can only wiggle and squirm.
"Becka, I can't believe what happened last night. My boyfriend gave me anal, it felt so good, after an hour or so I gave him a Squimmy Jimmy. Now I don't gotta worry about him cheating on me anymore!"
