6.
A name for a rather large, hefty girl, most people consider a tom boy. Also others think she is lesbian, and most friends are guys that think she is "one of them." She also has very manly-ish features and most often doesn't enjoy what most girls do. Most people are afraid of her.
"Hey there's Big John."

"I sure wouldn't wanna get into it with her."
