Cast Overreaction on a post, and then unclick your reaction so that it disappears. This psyches out your opponent, and also hinders their ability to gain extra EX from other people clicking on that reaction. Not entirely sure of how useful this tek is or if it's worth burning your EX meter, but just throwing it out there to see if anyone might know how to put it to good use. Peace and Blessings x

this tek has been used a few times by some of the unsung Masters of posting, initially mistaken for an exploit

its some top-tier stuff tbh

Added bonus to this tek-dek is that if someone comes along later and clicks the same reaction you left previously, they'll be pleasantly surprised by a giant reaction out of nowhere
