"Where the fucking squash at!?" is a really stupid, meaningless expression to yell when walking into a party or other social situation to be absolutely obnoxious and dumb.
Plays on the word "sqad" meaning group of people or friends. "Where the squash at!?" "Where the fucking SQUUAAASHHH AT" "Where dat squash!?"
*enters a party*
Gretchen: YO BITCHES. Where the fucking squash at!? I'm finna get LIT tonight !
Regina: omg . Hahaha you're so fucking dumb Gretchen, please stop trying to make the word "squash" happen. It's NOT going to happen.
Alright, I won't elaborate on how I found this out, it's a long story. Let's just say that it took me and a friend buying the wrong thing twice, wasting money, and being yelled at for it. If a Korean recipe calls for yellow squash or blue pumpkin, they probably mean zucchini. Damn, they can hardly speak the language sometimes yet they decide to make up a few words of their own. I don't understand it, I really don't :<
Mother: You! Get me..yellow squash!
Me: *leaves and comes back with yellow squash*
Mother: AAaaghh! Stupid! That not yellow squash! Go get mommy yellow squash!
A Pakistani-American. It is unknown if this is true in other countries, but in America, people from Pakistan and their offspring LOVE butternut squash.
