Qwoop is a funky way to back up sumthing with excitement. Alternatively it can also mean 'wow' or 'wooo'.
My friend discovered this wonderful word on sum message board
I'm goin to *sumwhere nice*. Qwoop!
I'm going out with that nice guy/girl! Qwoop
From the term "woop"
A "q" was added as a typing error, and was adopted. Now used as a more passionate version of woop, to express sheer excitement.
Can also be used as qwooooooooooooooop (by adding extra o's to show the amout of excitement)
Mest are coming to newcastle! QWOOOOOOOOOOOP!
