a toxic person (usually male) on roblox, usually accompanied by the robloxian 2.0 body, stichface or headless, messy black hair layered over another hair of the same color, and korblox leg. They often set their proportions to the skinniest possible, warranting the name 'slender'. Usually used as an insult, 'slenders' have coined the term for themselves, along with cnps. (copy and pastes), these are the female counterparts to slenders, and have the same characteristics as shown above.
"i HATE slenders and cnps! why dont they just leave me alone when im in game!"
" I love 'slender and cnp hangout on roblox!"
" slenders are ugly."

Get the Slendermug. A trend in Roblox which was made in probably May 2020. The boy version of a copy and paste. All of them look the same and they usually have two or more hairs, a stitch face, edgy accessories, 2.0 body package, korblox or skeleton leg which is optional, and tall is a must. They have a very bad reputation or stereotype such as being an online dater or acting 'toxic'. Which can be true. Most people think that all slenders act the same. But not all of them do. Some can be nice some can be rude. They get a lot of hate and I can definitely understand because it's probably annoying to see everyone dressed the same. Its kinda ugly in my opinion. And by now I think slenders and copy and pastes are low key dying. Overall, I think we prefer the real Slenderman.
