A sex act in which, while doing someone anally, you suddenly pull out and insert a lightbulb into their asshole.
Dude, I totally gave that chick an Uncle Fester. You should've seen her ass light up!

Whilst receiving a good and proper skullie, it occurred to me that this was a fine time to introduce her to my "Filthy Uncle Fester". I gave her the old reach-around and pulled a fine example of last Tuesday's meal from her behind whereby I tactfully smeared it across her upper lip while my exploding fecal deposit caused roiling, brown toilet water to splash upon her chin.

Step #1 person one lies down on the ground wearing uncle fester's coat pulled up to expose his erect falice.

Step #2 the second person does a hand stand over the top of person one's erect falice

Step #3 the second person begins to slowly Lower themselves down until the erect falice is as far down their throat as humanly possible (no visible falice is preferred)

Step #4 person one then places a lightbulb firmly in the second person's anus and then lays back down once the bulb begins to glow.

Step #5 enjoy uncle festers nightstand
That party was wild last night. I saw some chick get an uncle fester's nightstand on the kitchen counter
