Grrr is used in online gaming to signify disappointment and anger at not getting picked for the team.

It originated from the online MMORPG World of Tanks when a clan member actually growled on voice chat at the clan leader for not picking him.

Clan leader: "... Bob, John, Simon and James: That is the team."
Unpicked clan mates: "Grrr!"
