I particularly like "****" and "shit", I say them quite often. I find it particularly amusing to replace a word in a title with ****. "Donky Kong **** Returns", "Million **** Baby", "Slumcunt Millionaire", "Bravecunt", you know that sort thing.
I also like phrases like "laughing like a ************".
And I like refer to animals as "doggy" when they are clearly not a doggy, though it's better when the animal is somewhat dog like, like a panda or sea lion. I like to call pandas "big ol' doggy" in a hick accent.
I really like immitating Jericho from Fallout 3 and using the word "asshole" multiple times in one or two sentences.
Oh and I like putting qoutation marks around things that actually need them.
When the "inventor" of mayonnaise "died" of "food" poisoning caused by injesting "his" own "product", the world "blew" a sigh of "relief".
