If you can't think of anything to say then don't say it, there is no need for filler words. Smart people speak to be heard but idiots speak to speak.
i'm not gonna constantly stop in the middle of sentences in place of filler words, man. i'm pretty sure that's infinitely more annoying than "like."
+ look who's forgetin' talking. god damn you are a treasure.
on the topic of more hated things: people misspell words in things that are going to be there forever (e.g. video descriptions, forum posts) and then refuse to fix it
