Team Fortress 2 Scottish Handshake

thingiverse

In Team Fortress 2, players are known for extending their middle finger and making a fist to show dominance on screen. The signature hand gesture bears little resemblance to the real-world traditional shake that implies agreement or good sportsmanship in social situations, such as closing business deals over handshakes of welcome mat kind and so on, it really just is what they do - its quite simply another method by which players have at each other, usually during the match, although many gamers do use this particular gesture throughout matches in general too.
