A singlelingual is a person who is truly by themselves. They are incapable of making any meaningful connections, and they can also not speak more than one language.
“Hey, have you seen Jerry around recently?”
“Nah, he’s a total singlelingual.”
“Wow, what a loser.”
What the fuck are you even talking about? What kind of words even are those? Stick to Australian if you're going to talk to me cunt, I'm single lingual, yeah?
