A sad but surprisingly affective phrase often used by Eustace to scare the crap out of Courage in the animated cartoon, Courage the Cowardly Dog
. When scaring someone using this phrase, be sure to wear a mask larger than your body.
Eustace: Hey ya stupid dog, look what I got for ya'...
*turns around and puts on giant scary mask*
Eustace: OOGA BOOGA BOOGA!!!!
