You know what is really funny? Words that aren't supposed to end in "tastic" but do. Pay attention and you will hear the use of these spastastic words. Try using them yourself. For example, if you were watching a movie which you thought was good, you might say, "This is movietastic!" Or if you saw a guy with plummer's crack, you might say, "That's cracktastic!" If you've never heard this, you should try having a conversation with my brother-in-law, Danny. He'll get you up to speed. He's tastictastic.
But the really funny thing is seeing this phenomenon used in marketing. OFF has a whole line of bugtastic products, which they seriously term "Skintastic!" It's right there on every bottle or can of bug repellent. In print. In large letters.
I'm not saying this is wrong. I'm not saying it is right. I'm not saying it is annoying or humorous or a good marketing ploy. I'm just saying there it is.
This tastic quality is especially important to our family, since we live in a swamp surrounded by still water. The mosquitoes breed, and then they come in hoardes to my house to suck the blood out of my children. So for us, Skintastic is necessetastic.
