How do you say asshole in chinese?

Yeah, I'd like to know what it sounds like..coz I pretty sure I got called that when I got chinese take out last night..
Del always gets the same thing..kung-pau chicken...always.
for some ungodly reason,last night I circled on the menu...GENERAL TSO's chicken..not even remotely the same,not even in the same section..
WTF?
The lady was nice enough to allow me to reorder the right item, but gawd..I felt like such a dork...I was sure I had ordered the right item..
