A gayish, fussy way of saying "merci" in France these days which could eventually catch up in non French speaking countries - hopefully not.
Paul-Henri: I bought you some pink roses.
Alphonse: Oh, that's so sweet, merki!
noun: A merkis is a postiche
that protects the upper anal
region more specifically your 'crack,' sphincter, and buttocks from the harsh elements of day to day life. Generally only worn by village people impersonators and baby eskimos
to keep their baby
derived from the English word, merkin, meaning pubic postiche.
That Frat Bunn is such a big gay merkis!
Look at that baby eskimos hiney! It's got a merkis!
God dammit PJ! It smells like hot merkis duck butter in here!
