Single goggles

When you're single, this can occur at any point, and everyone around you starts becoming attractive and you start to develop pointless crushes on anyone who spends any kind of time with you.

"Dude, I think I am falling in love with the girl who sits behind me in chemistry."
"She has a boil on her chin, and smells like old baking grease... it's just the single goggles, bro."
