For something weird: "That's as queer as a football bat"
For an ungly girl: "She looks like she fell out of the ugly tree and hit every branch on the way down."
"She looks like her face was on fire and someone used a pick axe to put it out."
Variation of "I'll be damned":
"I'll be dipped in **** and rolled in sugar."
Vincel at the Taylor Cafe once told me that he thought a really big woman could "Kickstart a 747"! Classic!
My dad used to see a good-looking woman somewhere and rate her on the Budweiser scale. "How many Clydesdales it'd take to pull her off my face!"
I like the use of the term "Mickey Mouse" to refer to something as insubstantial, flimsy, or cheap. My grandpa uses it all the time. Disney must hate that colloquialism.
I've never understood the following country sayings:
"Hair-lip the Pope." (see, e.g., David Allen Coe lyrics)
"Hair-lip the governor."
I don't know what they mean, nor have I been able to infer the proper context for their usage. Still, I've heard my redneck brethren spout them for years.
My mom always says, "If it hair-lips the pope and every cow in Texas." I guess it just means, "no matter what." Can you imagine how serious you must be about doing something if you don't care if it causes the pope and every cow in Texas to end up hair-lipped?
Oh yea, almost forgot:
"Hotter than a freshly-****** fox in a forest fire!" and "Hotter than two squirrels scewing in a silk sock!" Gotta love the illiteration.
For the fat guys:
You look like a fartsack full of doorknobs.
(I've never in my life heard the term "fartsack" except in Marine Corps boot camp to describe the sheet-like bag, which I've also never seen outside of boot camp, that wraps up your mattress in place of a fitted sheet.)
