1)Year 2000. (Y=year, 2k=2 times k, k being short for kilo which means 1000)

2)Computers only counted the last two digits of a number, so they didn't know the difference between 2000 or 1900. This would cause various problems with dates and finances, and would cause a big mess. People were panicking and saying that when 2000 rolled around, all the computers would crash and the nuclear bombs would go off or something.
Good thing I'm Amish, Y2k won't affect me!

Short for "the year 2000." It's usually used to describe a fashion style of the early 2000's. It consists of bright pinks, purples, and yellows. Some low rise denim skirts or jeans also fit this vibe/aesthetic. Form fitting clothing is a huge staple of Y2K fashion. Buttonup cardigans, tie-front shirts, and sweaters are a huge part of the trend. It's soo cute ;p
Her fluffy pink hat is SO y2k vibes.
Marissa, your aesthetic is totally y2k.

The twentieth century after BC; the year when computers and resources were supposed to explode,implode, and crash all together.

Short for "year 2000". Also known as the "Y2K scare" or "Y2K bug".

Since computers only counted the last two digits in a number (e.g. 1984 would be 84), they would reset 1/1/2000 to 1/1/1900. This lead to everyone thinking all of the computers would crash since the PC's wouldn't know what the date was and all the information would be lost forever.

People worried about their money, jobs, houses, loans, all that jazz. We all went berserk and thought we were gonna go back into "caveman times". However, it didn't happen.
Three minutes before New Year's Day 2000:

Person A: OH FUCK, IT'S Y2K! HIDE IN THE CLOSET!

Three minutes later...

Person A: It's 2000, now what?
Person B: I like yellow things.
