"Slender" can mean different things, it truly depends. Some examples are:

1-Slender man (Game/character)
"Slender man" is a character in a video game named "Slender". Slender has a black tux, covering all of his arms & legs, including feat. His skin color appears to be a pale white, white a possible greenish tint. It's unhuman.

Slender/Slender man is a horror game where you search for 6-7 pages (I haven't played, personally - so I'm not actually to sure.) in a dark forest while Slender man chases you.

2-Slender (Roblox - Slang)
On the free online game, "Roblox" there is a slang term, "slender". Slender folks are boys who appear to be extremely tall, and they typically have the black colored "Beautiful Hair For Beautiful People".

Some other things they often where are:
-Black tuxedos/clothing.
-Any faces, excluding non-robux ones.
-A "bone" leg.
-A "peg" leg.
Slender rarely/never refers to girl players, and is mainly/only directed towards boys.
A "slender" often online dates, of course it doesn't go anywhere, though.
Some GAMES they often play are:
-Ragdoll
-Group Recruiting Games
(Other)
Ragdoll is often the common attraction for slenders, mainly because the "movements" allows for more "intense" online dating.
Slenders are frowned upon in the Roblox community, however I'd say about the other 23.65% of the community is fine with them, mainly because they're slenders, too.
(GAME) "I played slender last week. Big mistake, I'm still having nightmares."

(GAME) "Dude, did you hear about slender? It's scary."

(ROBLOX) "Oh my god, I think that's a slender, do you?"

(ROBLOX) "Ew, it's a slender. Let's go."

Used as noun, verb, adjective or honorific: a pejorative term describing an individual (usually on the fringes of a friendship group) who generally (and often unintentionally) ignores usual social protocol. Their actions and behavior are often described as "creepy", "overly friendly" or "overly tactile". Derived from the 'slender man' internet mythos; a tall, human-like monster who allegedly skulks around silently, stalking individuals and stealing small children.

Players who are thin, taller than normal, and tend to have a punk-style look in Roblox are called Slenders. They are mostly male characters, but sometimes you can find female Slenders in the game as well.
The slender is in love with the copy and paste.
