nub nade
A nub nade is usually used in on-line gaming when someone gets off a random and/or lucky grenade. The attack has little or no thought behind it and is usually a last ditch effort. Nubs tend to do this rather often, so the 'technique' was named accordingly.
Out of game it is used to imply a "cheap shot" or "low blow".
