Mexican sound of disapproval. Anything in put in front of it will be discredited.
(Rough quotation from Gabriel “Fluffy” Iglesias in “I’m sorry for what I said when I was hungry”)
Friend: I just graduated form college, top of my class!
Mexican Friend: *Tongue click* Ahhhhh
Friend: Fine, I’ll work at Burger King!
(Again, from the same comedian and same show)
