Butch spirit

[Chicken Sandwich]

I was just watching "The Big Bang Theory" and at some point Sheldon said:

Please reserve that butch spirit
for the lanes.

What is a butch spirit? I couldn't find it anywhere.

Thanks

Not a teacher only a native.

"Butch" means manly, masculine in appearance or behaviour. So if you have a "butch spirit" you act very manly, not like a lady or girl would.
