Any Spanish word which includes the "trilled" R. For example, if a word starts with "R" in Spanish, you are supposed to flutter your tongue as you say it. I am always tempted to extend the length of the trill!

many of us [especially in america] seem to lack the gene which codes for ability to trill/roll R's. but i am prone to clumsy but enthusiastic rhotacisms myself. anyways, my favorite funny words of dubious etymology, are-
sheemoo [a minced oath]
jeez louise [a minced oath]
shazzbutt [all-purpose euphemistic expletive]
d'oh! [ditto]
doodly-sqwat [a minced oath]
yabadabadoo [fred flintstone's favorite cheer]
shyamanama [a minced oath]
steatopiguous [means having huge jutting buttocks]
wish sandwich [ghetto slang for having 2 slices of bread and no meat]
nosegay [a bunch of flowers, but it sounds funny]
reintarnation [being reincarnated as a hillbilly]
carbuncle [a ruptured, absessed boil]
spoonerism [unintentional transposition of words or syllables, e.g., "tiger's woody"]
indubitably [without question]
philtrum [that little notch thingie on your upper lip beneath the nose]
foofaraw [noisy overreaction or flashy decoration]
redumbancy [repeating the same mistake over and over]
lugubrious [refers to exaggerated sadness, but the word itself just sounds funny]
caddywampus [for something to be disorderly]
obsequious [to be apple-polishingly ingratiating]
judas h. tap-dancing priest! [a minced oath]
daggone [a minced oath]
inka dinka doo [simply means inka dinka doo

¡aye carramba! [a euphemistic expletive made famous on "i love lucy"]- i love exaggerating the double-RR trills of this phrase.
