What's the Good Word?

Here are a few that I have enjoyed over the years:

Basilisk--a legendary reptile with fatal breath and glance.

Callipygian--having nicely formed buttocks.

Espiègle (es-PYOG[l])--frolicsome, roguish. (To paraphrase an observation by a character in a skit from Mad TV, "Richard Simmons performing rhythmic aerobics while dancing with a rainbow flag would not be as gay as that word.")

Mundungus--foul-smelling tobacco.

Oogamous--a form of gamete reproduction wherein a small mobile male impregnates a large immobile female. (I've known some couples like this.)

Sir-reverence--An archaic term that could mean either "an expression of apology before a statement that might be considered offensive" or "a lump of human feces".
