Masterdebater (noun) - Another name for really good debaters. Not to be confused with "masterbater," although since most debaters are weird, nerds, and freaks, many of them are also masterbaters.

Andrew: what the fuck?!

Being an expert (master) at (debating ). I first heard this phrase in mid-2025 on the telly programme, "South Park" -- specifically in the season 27 ep. 0 episode, titled "I Was Masterdebating Again," where Eric Cartman locked himself in the bathroom and was masterdebating with several college-aged women on his laptop computer whilst sitting on the shitbowl.
{Eric Cartman's mom}: Eric are you alright in there?
{Eric}: Yes I'm fine mom, I'm just in here masterdebating!
{Eric}: Yes I'm fine mom, I'm just in here masterdebating!
