I'm no PvPer. In fact, I'm almost exclusively PvE. (So no idea if this would ever work in a real organized battleground)
I got dragged into a random battleground with some guildies for giggles one night, and we got into one of those Warsong Gulch clone battlegrounds.
The most hilarious cap I got was simply standing on our flag spot with their flag and Gorefiend Gripping everyone into my Breath of Sindragosa. Nearly wiped out that group that came to kill me by myself.
