Somebody who is extremely fat and into men/boys. they are usually super ugly, actually always. You do not want to be near them, as they are super nasty and just perverts and creepy. If male, they are also incels and basement dwellers.
"Dude fucking run, Deelen is coming, he is nasty as fuck"
"You forreal, he is actually coming? That's my worst nightmare"
"Yes, run now!"

Get the Deelen mug.
Deelen, noun, a poor indian spelling of 'dylan'. This person is a very musical person.

Deelen is never a Neil, because Neil is in total better than Deelen.
1. Oh my goodness, he is so talented with music! He must be a deelen.

2. Oh wow, he just did everything a Neil wouldn't do, he's a deelen.
