A hick city in southwestern Ontario. Basically a typical middle-class town full of white people and the occasional crack head. People have heard of it but no one really knows exactly where it is.
Toronto boy: So where you from dude?

Guelph boy: Guelph, eh.

Toronto boy: Is that up north?

Similar to a girl queefing, a guelph is when the penis of a man releases air out of the meatus of the urethra, making a soft "fart-like" sound.
Dude, so I was sleeping with this chick, and after 3 minutes, I guelphed. I was so embarrassed I had to stop.

Predominantly white, city with extreme rural vibes in southwestern Ontario. Rumour has it guelph has an overwhelming manure odour...everywhere. The type of place where if you didn’t play hockey and have flow you were probably a loser in highschool, and if you did you probably say #guelphforever. Surprisingly produces a lot of hot girls. Yeehaw... see u mediocre ass wipes at boots and hearts.
Toronto Guy #1: That girl has the nicest ass, watch me give her rinse tn

Toronto Guy #2: don’t waste your time man, unless you play jr.B Hockey , are her cousin, or regular franks shes not interested. She’s from .... Guelph.
