A person that is one part schmuck, one part nerd, and one part geek. This person is highly irritating and abrasive, and has embedded himself into a social network or group that he is not welcome in, but is unaware of this fact. Schnergs typically talk at an unreasonable volume, and with improper frequency, usually in unfortunate circumstances and with por results. Getting rid of these people is next to impossible.
Jim keeps following us everywhere we go, telling his bad jokes along the way. Let's ditch this schnerg.
