Anything and everything to do with the Hi Hat, I'm beyond terrible with it.
Actually went to a party a few weeks ago and sure enough there was a Drum Kit, and as usual (with every other drum set I've ever come across at a college party) it was only a single kick and had awful cymbals.
I played a few beats, impressed a few girls (pretty sad tbh, I played the simplest stuff... Like stuff I could have taught someone who's never picked up a pair of drum sticks in probably like 20 minutes) but was more so just disappointed with myself that I couldn't work said Hi Hat.
Starting to regret going right into Double Kicks rather than mastering the Hi Hat first
On a side note, Non Drummers are seriously impressed by the simplest beats.. Playing paradiddles around the kit makes them think you're the best drummer ever, it's ridiculous.
