When a person is quiet when they walk. This usually leads to the person with Slender syndrome to scare the living hell out of any unsuspecting victim who doesn't hear them coming.
Person 1- Dude, that girl over there scared the hell out of me the other day.
Person 2- How? She looks so innocent and nice.
Person 1- She has Slender Syndrome. She's innocent and nice but quiet as hell. Watch your back.

 Get the Slender Syndromemug.
Get the Slender Syndromemug. Roblox Boys (Mostly 9-13 year olds) who change their avatar look to be very tall and have the typical "Slender" look, they are mostly accompanied with a Roblox girl called a "Copy and Paste" (Copy and pastes are mostly 9-13), they will go in Roblox games such as Ragdoll Engine, Hugging hangout and "cuss here" games. These people are very rude for the most part. These people get the "slender" from TikTok. If you criticize a slender in front of one, they will say stuff that is just pathetic.
