Slender

A Roblox player who usually has a very slim and tall avatar with accessories such as Stitchface, black clothing, bypassed clothing (such as having a shirt with profanity or an inappropriate image), and an absurd amount of hair accessories. They are known to be generally toxic players, and most are under the age of 16 and constantly use phrases such as "mic up". They're also known for online dating other slenders in CNP (copy-and-paste) hangouts.

Roblox has an abundance of slenders, it's like a fucking parasite on the community.
