Stalk-flooder 

Someone on your friend list who clandestinely likes or comments on your old pictures, so as to draw the attention of the world to your veritable foolhardiness, with the intention of causing immeasurable trauma, sometimes leading to Foticide(means deleting your own pictures, not to be confused with foeticide )

Being the stalk-flooder she is, she liked my old prom picture and subjected me to the ridicule of the whole world.

Stall Flooder 

A certain individual who flushes a clogged toilet in a crowded public restroom, causing poopwater to flood the ground. Usually those in the stalls around this certain individual are forced to abandon their thrones and become very angry. This certain individual will laugh and run away as to escape the ire of his/her victims.

Bob: Ah....I finally get to sit down and empty my bowels

Fred: Haha. I'm going to flush that clogged toilet to piss Bob off.

Flushing sound followed by the sound of cascading water.

Bob: Aaaaaaa!!!!! What the fuck!!!!!!! Damn Stall Flooder!!!!
