Filip aka Felipe aka Philip aka Phelipe etc.
Nickname from Filip in Serbian, is Fico (Ficio if you read it like italian ) , and when you reverse it ( cause of the anti-ACAB slang, we use, so ACAB wont understand what we talking about ), it becomes from Fi-Co to Co-fi = Cofi.

Mates calls me Cofiliano( Ci-ofiliano ), cause of my italian style ( w/e )..
