TSTO 

Too Stupid To Operate.

Usually describing someone who seems too stupid to manage doing something without serious help. They really seem perpetually clueless and inept at something.

That guy back there tried to fill up the cup with the lid still on! Seriously TSTO!

tstoned 

The process of sneakily showing someone your testicle. This is done by pulling out your nut and holding it at your waste and then pulling your shirt up to expose the testicle.
