An ongus is a very irritating person, who is obese and can't own up to the trouble they have caused, typically in a boarding school or work place. An Ongus will tell
On you for retaliating or giving them a right Beatin' but won't admit that they started they issue. An Ongus will have very poor personal hygiene and a poor diet.
Bro, Ongus snitched on me but won't own up to what he did, he also tried to frame me the other day!

Friend: did you see how much Ongus ate for lunch!?
