Malcity 

a nickname for a socially awkward friend who often brings up very inappropriate topics. Can also be funny at times but its the kind of funny that is only funny because Malcity says it. Also makes funny videos about broads.

Friend - "Yo malcity go talk to that girl it would be so funny."
Malcity - "ok"
