look up any word, like fleek:
 
1.
A particularly strong kind of Ecstasy / MDMA pill. Pokeballs generally have a reputation of containing a solid dose of pure MDMA -- though not every "pokeball" pill is guaranteed to live up to this expectation, most do.
Pokeballs are thicker than the typical MDMA pill, come in a variety of colors, and usually are stamped with a logo (like a butterfly) on one side and a "pokeball" score on the other side.
"That white butterfly pokeball hit me so good last night I only needed one pill for the whole night!"

2.
A ball where a pokeyman is stored in.

There are different kinds, but the classic red and white one is most popular.

Before you cum, you place one of your balls halfway in the anus* of your significant other and pull it out. When you're just about to cum you scream your favorite Pokemon and "I choose you". To complete the act you cum on her forehead and your shit covered ball enters her mouth, thus cleaning your ball-sack.

*This should make the ball look like a Pokeball
*Performing Pokeball*
"Gyrados, I choose you!"
