Something that is totally, astonishingly, stupendously good.

"Q" shortening of Thank You, but can be used in awkward/funny moments by just saying "Q".

The stupidest fucking letter ever. It’s literally just an O with a little line through it. Like how lazy did the Phoenicians have to be to make such a stupid letter.

Q is a letter you should know this idk why you are looking for a definition for a letter

Q is a british music and entertainment magazine, published monthly in the United Kingdom since 1986.
It is well known for its 100 Greatest lists, ranging from "100 Greatest Albums" to the "100 Greatest Rock Lists".
Some people have compared it to Blender, an american magazine.

A Federal Q2 siren, the last mechanical siren made for a moving vehicle. It's almost always used on fire apparatus.
It's loud as hell. R=The next best thing to playing an MP3 of "Move bitch! Get out the way!' on a badass PA system.

I'll fuck you later. Used with "X" (Kiss) and "O" (Hug) at the end of a letter, card, or conversation with your fuckbuddy. Derived from how the captial letter "Q" looks.
