Getka'd is similar to the phrase "GOTCHA". It means that one person essentially trolls the other person so hard in 'real life' that all of their plans, past and future, implode in their face.

Someone who is possessed by clout chasing. The original human is now gone and a demonic entity that feeds on clout is all that is left. An empty shell with no control of their actions, forced to blindly react to situations they think will bring them attention.
