My 2nd speculation
When a Pokémon receives an indirect damage (Stealth Rock & Co., Poison, Burn, Rough Skin & Co., Confusion, Rocky Helmet & Co., ...) increase its Speed 1 stage.
First sounds kind of like... Hustle? Just a more complicated variant. XD;
Also as for the second, SR and status is way too common, so I think it wouldn't really be the best - especially given we have Quick Feet for that, for the most part anyway. :x
