There's a sticky thread called "the answer to 'what binding'" which you should probably read (along with all the other stickies) before making stupid unnecessary threads.
"What you are feeling is a base burn. The toilet bowl cleaner probably has a really high pH , and therefore must be neutralized with an acid that has a really low pH. So basically, you just need to stuff your asshole with the most acidic shit you can find, battery acid, sulfuric acid, nitric acid, whatever you can get your hands on. its gonna be a chemical showdown in your asshole today my friend."
