Gronk 

A complete loser and try-hard who has low self-esteem and minimal confidence in themselves. Will do anything to please someone and has no opinion of their own. Often broke, of low-intelligence and limited prospects for success. The embarrassing moron of the group that everyone pretends they don't actually know

When one approaches your group waving and smiling:

You: Check out this gronk!
Your mate: Ha what a gronk
You: How's this gronk, acting like he knows us?!
Your mate: Keep walkin fukn gronk!
