wtf is this exactly?

A quick google search tells me:

TeamSpeak is flexible, powerful, scalable software which enables people to speak with one another over the Internet. TeamSpeak consists of both client and server software. The server acts as a host to multiple client connections, capable of handling literally thousands of simultaneous users. This results in an Internet based conferencing solution that works in a variety of applications such as team mates speaking with one another while playing their favorite online game, facilitating inter-office communication among co-workers, or simply for personal communication with friends and family.
