1. Someone who has appeared to have or smells like they swam through several miles of sewage, fresh from your septic tank. A derivative of the term Botticrease, which means 'Buttcrack', a Bottifish is someone who looks like or smells like they have just swam in a pool of shit.
2. Someone who genuinely sucks at any electronic game.
*Sniff...Sniff...* God! Get away from me, you Bottifish!
You have the skill of a Bottifish!
Damn...Cross the street, the guy coming up looks like a Bottifish.
