You mean the Team Rocket guy (yes his real name is BUTCH) that's with the other girl, and they rival with Jessi and James cause they're all morons?
there is...
"Biff", "Bill", "Butt-ch", "Buffy", "Bob", "Hutch", "Butcher", "Patch", "Botch", "Chuck" or "Hootch."
I'm ABSOLUTELY sure there are more than that, I just watched an old episode and they called him all those and some, I just can't remember, and can only sit through so much Pokemon in English.
