Hax refers to things that are considered cheap, unfair, or kind of like cheating. Bright-powder is considered Hax as it lowers accuracy. Paraflinch (like Jirachi with Iron-head and Thunder wave) is considered Hax because it gives you a pathetic chance of moving. Quick claw is also Hax. Hax is a relative term so it really depends on who you are battling or what website/tiers you are using. Have fun and Happy Hax lol XD
