The thing with 4 bet bluffing is that you probably have 0% immediate fold equity on the flop, which makes your bluff more expensive as you're now risking 1.5 big bets on the turn to win 5.5. Not counting river fold equity, this means we need 21.4% of the pot to make the bluff worth it.
I think we need J

to run a bluff after he 3 bets the flop.
Also, he may be baiting you to try to develop a turn donking range. Hmm. I wouldn't do it.
If you don't 3 bet preflop with monsters, then I think he's more likely to just call your flop check raise hoping to raise the turn with his monsters, which argues for 4 betting the flop and going from there.
If you do 3 bet preflop sometimes, then I think he's more likely to go for the value on the flop, which makes the flop 4 bet a little thinner.
Though he probably knows all of this and was just plain messin with you at what he felt was a neutral ev decision.
