A disorder affecting most butches in the lesbian community causing them to hate all other butches. To view all other butchs as a threat. Thinking every butch lesbian wants to date your femme.
Butch A dates Femme A. Butch B is single. Butch A lesbian nods to Butch B. Butch B approaches and extends her hand to Femme A. Butch A reaches and grabs Butch B's hand tightly while using her other hand to jerk Femme A uncomfortably close to her side.
This is a classic example of butchinsons.
