a way of describing something to be good, or to describe your mood. deriving from the MSN emoticon that is a thumbs up, the code being (Y), or y in brackets.
can also be used randomly by shouting it out and putting your thumbs up cheerfully.
often used by computer nerds or just general cool kids.
i got an A* in my test, y in brackets!
person 1 : how was the show?
person 2 : y in brackets, i loved it!
these are what brackets do when you use them in urbandictionary between every single flippin word in the deffinition. its also really god damn hard and slow to type. but i think i'm finished.
