A teeg is usually stereotyped as mellow and is not absorbed into other people's problems

2.
An inexperienced gamer (Preferably a young kid) who has nothing to do except talk shit on the mic all day in Video games.

Or... basically a noob.

Plural version of the word would be... "Teegz"
"Man! Omar is such a Teeg!"
-"I know man, all he does is talk on that stupid mic!"
