A word to use when you are at a loss for words. Derived from the Spanish word "jamas" (ha-maas) meaning "never again." When used in English, jamas sounds just like the Palestinian terrorist group HAMAS and so intonation must be changed to "hamus." Extending the last syllable, you get hamoose. In noun form, one can use "moose" to describe a person who has committed an action worthy of a "hamoose." Other variations include "moose abuse"(excessive use of the word "hamoose"), "moosehead,"
"Jesus Christ you just spilled your entire lunch on my shirt. Hamoose!"
"Yeah man, you're a moose."
