So earlier at the battle maison as I was battling the opposing trainer once had 2 Slakings! This was in singles by the way.
Also I found a trainer with the name Dick.
I thought Gamefreak banned that name from Pokemon.
You must have just been very lucky! To get the same poke in the RNG is a rare occurrence.
It's a trainer's name not the name of a Pokemon, so therefor you Can in fact verse a trainer called Dick
