Stretchy Gretchy is a phrase for a "thick snicker" boy that magically appears at class before everyone, even though you previously had passed him so you would assume that you would arrive to class before him. He has a distinct moustachhheeee as an eyebrow. He loves oranges and at lunch announces that "I like my girls as I like my oranges, Juicy." Girls tend to think that he has a skinny penis, and sultanas.
"Yo it's stretchy gretchy"
"YO GRETCHY"
