JM Simp

The JM Simp is a sub-species of mother fucker, as he is a major simp, and the opposite of an anime protagonist chad. He thinks that he pulls, but the only time that a girl has interacted with him was giving him a baked muffin in the kitchen (where women belong).

Did you hear? That JM Simp was found outside of Camberwell High School accepting a baked muffin from a stupid woman!
