Euphemisms

I wasn't sure if everyone would know what a Euphemism is so heres a definition: "An euphemism is the substitution of an agreeable or less offensive expression in place of one that may offend or suggest something unpleasant to the listener. It also may be a substitution of a description of something or someone rather than the name, to avoid revealing secret, holy, or sacred names to the uninitiated, or to obscure the identity of the subject of a conversation from potential eavesdroppers. Some euphemisms are intended to be funny"
I think Euphemisms are really cool. In fact I wanted to suggest some that I think should be more frequently incorporated into our everyday vernacular (if you have you think deserve such a status please comment).
"Wipe your plow" - akin to getting your trash kicked, or a can opened on you
"Willie Benillies" - infatuations and such feelings; i.e. "Bro, shes got the willie benillies for you."
"Maxes my MU" - maximizing of marginal utility; anyone who's taken Econ 110 knows that this is a good thing
"Expiration dater" - one who begins dating with a termination in mind
"Garons babarons" - 'guaranteed' - from pigeon english
Anyway - these are just a few of hundreds that I like. I think we should all use them more - they're interesting and make life a lot happier. Please let me know if you have any you think I should add to my vocab.
