That was the joke. Relax, I'm not going to have an aneurysm because your text is ugly. To answer your question:
First off, I imagine this would be better-suited to a bulky pokemon that would be capable of walling the opponent, or a faster pokemon that can pull off the RP before it's hit by a super-effective attack that will be negated by the new ability. For example, Infernape outspeeding Vaporeon to Role Play its Water Absorb to negate the incoming Surf, then pummeling it with CC.
Problems are: first of all, no bulky OU pokemon learn Role Play, so that strategy is out for OU. Mew, Latias, Cresselia, and Arcues learn it for Uber. Uxie, and Mesprit learn it for UU.
As for the offensive strategy, Infernape and Luke work in OU, Blaziken and Alakazam work in UU, and Mew, Mewtwo, and Arceus work in Uber.
Thing is, it's very situational. First off, by using Role Play, you're losing 1 move slot. Secondly, it would require a great amount of prediction and baiting attacks that may, in the end, just not be worth it. Example: sending in Luke as a revenge killer against a Heatran you know isn't scarfed. Luke Role Plays Flash Fire and absorbs the Fire Blast first turn, second turn OHKOs with CC. Why not just OHKO in the first place? Also, you're hoping that Heatran doesn't just decide to Earth Power OHKO on the first turn.
To put it more generally (let's use OU for sake of argument and simplicity):
The pokemon that would be countered by Role Play would be:
Electivire (Motor Drive)
Flygon (Levitate)
Heatran (Flash Fire)
Jolteon (Volt Absorb)
Vaporeon (Water Absorb)
That's only 5 pokemon. Additionally, no OU pokemon that are weak to Electric attacks learn RP, so you can strike off Electivire and Jolteon off the baitable list. That only leaves the very situational reverse-counters of Infernape -> Vaporeon, Lucario -> Heatran, Infernape -> Flygon, and Lucario -> Flygon (assuming Flygon isn't carrying Fire Punch). Lucario -> Vaporeon would also work but Infernape -> Heatran would not because of EP. Basically the benefits would be so situational that sacrificing a 4th moveslot to pound Heatran and Vaporeon wouldn't be worth it as a general rule.
However, it could still have possible unforseen benefits for Infernape and Lucario, both of whom have fairly subpar abilities. Grabbing a Thick Fat, Guts, Levitate, Natural Cure, Pressure, Magnet Pull, Speed Boost, or Synchronize could well be worth it. It's just about whether or not you'd like to take a gamble like that. A Role Play set could make a good pokemon significantly worse by taking up a moveslot and wasting a turn, or it could pay off and net you a sweet ability, but still at the cost of a moveslot and a turn. Overall, it's an interesting idea but I can't see someone like Luke dropping a coverage attack or SD/Agility for RP.
