bonsai 

A small shrub that resembles a tree. So small yet so full of treeness.

I went to the store and bought a Bonsai tree.

bonsai sized 

A man with a small but well-developed, and aesthetically pleasing penis. Not necessarily a bad thing.

bonsai 

The ad that comes up everytime somebody goes on urban dictionary to look up something. Comes in on the middle of the page most of the time.

For men, for women, bonsai sandals. The coolest sandals on the block. (not)

When an Asian man perches on your shoulders and farts on your head.

Last one in the pool gets a bonsai whiff!

Bonsai Kitty 

A HUGE internet prank. some people stated it by posting fake petitions on websites talking about an invention called "bonsai cats" where supposadly young kittens are put in too-small glass jars so they would grow into the shape of the jar. the petitions include a link to a very elaborate fake website, which includes a place to order bonsai cat supplys (FAKE), a disscusion board (the people are FAKE), and pictures (the pics are fake, they never show a completed bonsai cat)
bonsai cats have fooled tons of people, don't be ashamed if you are a victim.
what do do if you were fooled by Bonsai Cats (and you're embarassed):
1)look it up on google
2)check out the website, the clues are all over the place
3)think of the people who crated it (you'll feel less pathetic)
4)it doesn't make you an idiot, the FBI (or something really big) had to investigate it just to prove it was wrong
5)think about who you heard it from: they were fooled too!

but the website DOES have this hella funny link to it that says "I CUBED MY CAT!"
...but thats fake too...
