Holo-teabag "easter Egg":

Have a hologram and kill someone. Tell your hologram to go right over the body's head (point the reticle right on the head of the dead body). Once it reaches the body, the hologram should teabag the dead body. This can be a great strategy, seeing as many people teabag, and if you kill someone out in the open and do the holo-teabag, it's likely that many people will shoot at it, giving you the opportunity to analyze their location.
