annoying

Things that annoy me:

When people type, "should of" instead of "should have", in reference to "should've".

When people add an 'h' sound in front of "what" to make "huhwhat?"

When people misuse the word addicting in place of addictive. In some cases addicting is appropriate, but I would argue it's better to use addictive. In its most ideal form, addicting is a verb, for example, "James is addicting Jeff to cocaine." It's more appropriate and most aesthetically pleasing to use addictive as the adjective.
