For your information, "retarded
American", walla is an actual
word. It is on the Scripps National Spelling Bee school spelling bee
word list for the 8th grade, and you can look that up right now. Yes, you were just roasted by a 7th grader. But the actual definition is, "A person who is associated with a particular type of work or who performs a specific duty or service." If you're going to make fun of someone, at least check your facts first; if you're not going to you end up sounding stupid.
