The character ~ is colloquially used in written form in some areas of the UK to denote sleazy, sordid, or otherwise base behaviour.
~ can also cover flirtatious behaviour with the opposite sex: you are never ~ with the same sex.
An ability to ~ is generally viewed as being a positive personality trait, unless it is used on a friend's mother, grandmother, or domestic animal. Being ~ to a friend's sister is usually acceptable.
The vast majority of the world's virgins, comic book fanatics, computer scientists, and train spotters wish they had some ~.
Remember that bird last night? I gave her some heavy ~ and she loved it.

MATE WHAT THE FUCK ARE YOU DOING? THAT BIRD YOU'RE ~~~ OVER IS HIS MOTHER!

I was nervous before my interview, but she was a woman so I gave it some ~ and got the job.

A very positive general exclamation. Derived from the tilde (~) character on a computer keyboard. In Internet culture, the appearance of tildes have come to connote strong reactions of happiness or approval. It stems from young computer users in highly excited states having a tendency to miss the exclamation point (!) key while typing, resulting in tildes becoming mixed with exclamation points in their writings.
"What's for supper, Mom?"
"Sloppy joes, Billy...and apple pie for dessert."
"Tilde."

"Ohmigawd, La Parka tilde tilde just ran in on the Triple H/Scott Steiner match! Tilde!"

1) A curved line, used over N in Spanish for the palatal nasal (the middle sound of "canyon" and "onion"), or nasal vowels in Portuguese (like in the city name São Paolo). 2) The character ~ (Shift-GraveAccent on a typical PC keyboard), used to similate smoke emanating from an ASCII cigarette: <//////*~~~~~

~

What more can I say? That above is a tilde but Urban Dictionary wanted more than "~" as a definition. Basically it's used in Spanish for some n's. but not all n's. Makes a sound like the middle n in "onion". This character does matter because of the difference in the words anos which means anus. And the word años which means years.
Tildes are so cool añd should be placed oñ more letters. Añyways, I just wañted to say that I thiñk they're ñeat.
