Pokemoning (also spelled "Pokémoning") is the act of dating multiple partners (or having multiple friends) in order to collect all the desired traits that's very likely to not exist in one single individual. Named so because you "Gotta Catch 'Em All."
Person 1: "Okay. I have my Sex Idiot, my Intellectual/Sophisticated Girl, my Tomboy FWB, and my Aging Squirtle. Who else am I missing?"
Person 2: "Pokemoning, I assume?"
Person 1: "Yeah. What do you think about a Crazy Tattooed Goth Chick?"
Person 2: "Gee, how many 'Pokemons' do you have?"
Person 1: "Oh, silly. The plural of Pokemon IS 'Pokemon.'"
