look up any word, like half chub:
 
1.
Pronounced "Yoo Gohn Lurn Duhdey!" (sometimes the "You" is eliminated), a viral catchphrase by Kevin Hart during his 'Alright, alright, alright!' segment of "Laugh at My Pain".
Kevin Hart explains that his father 'legitamately' walks in during his spelling bee, being outrageously loud—along with the dog on drugs—and repeating the phrase "Alright, Alright, Alriiiiiiiiiiiiiight!".
The phrase is used—but not limited to—mainly in high school to joke about how one will know what sex is, a long dick is, etc. but can be used in other various cases (or forms).
