A weak pokémon that you never use but you keep it in your party because it can learn HMs that you don't want your good pokémon to know because generally, HM moves suck.
Examples of good pokémon bitches:
Ratata,
Bidoof,
Nincada etc.
Pretty much either normal or shit grass types you can find in the beginning of each game.
All my
Pokémon are level 70!....except for my
lvl 15 Ratata. The only thing it's good for is bein my HM Bitch. Now if only it could swim and have wings....
