Gestures

Gestures are actions specifically used by players in multiplayer. They are used to show how they act or feel towards the game or players. Different kind of gestures show different kinds of feelings such as hate or joy.

Moonwalking
Moonwalking is a very known term used to describe someone who's offering "friendship" or just to show friendliness by moving back and forth while looking down. They are commonly used in the multiplayer mode "Free for All" to make small, temporary alliances, but usually they would end up being "friends" for the whole game. Moonwalking is preferably used on someone's dead body due to the fact that it's too risky to do it in front of them.

Sometimes one could instantly join your group when you're seen having a guy who you made friends with.

Shooting a dead body
Shooting a dead player's body is a action towards dead bodies of a player while they're still present. It indicates that the shooter hates you for specific reasons such as him being dominated by you, or else he's just trying to anger you. Doing this repeatedly when angered a player is more successful if you're very experienced with either a good or excellent weapon. It can also be used to challenge an allied player, usually when one is bored of hanging out with some players.

Shooting the sky
Shooting the sky is a sign of boredom during the match, or sometimes a sign of friendliness by some. This kind of gesture is also used during parties as no aggressive players are in the way. Occasionally, players would gather up and shoot lasers with either the Zap Gun or the Proton Gun.

Parties
A Party is the result of making a group of friends by doing several things such as moonwalking. During parties, some players would show off with their most unique equipment like gold-priced armor, or else shooting with a weapon. As of the Holiday Update (2014), many players would throw Stun Grenades at eachother and some would try to do the Gadget Freeze Glitch.

Trivia

 * Since there is no source of communication in the game, gestures would be used instead.
 * The majority of the Respawnable's players usually ignore gestures as they would simply ignore whatever they're doing and keep shooting at them. This highly applies to newbies and mid-level players.
 * Players at low-mid levels occasionally shoot randomly when there's no target. It is likely that they're bored or just wasting time.
 * There is a rare case that people wielding Bazookas auto-kill themselves when they get dominated by a superior player. It might be a sign of defeat, but it would be pointless since the dominant player would kill them anyway.
