"gleeris" (guh-leer-ees) is the possessive form of the armenian word "Gleer" (guh-leer) which translates to dick in english.
"gleeris" is used by armenians (particularly western armenians, or lebanese armenians) much in the same way 'fuggedaboutit' is used by italian americans. its short for "gleeris chem tnel" which translates literally to "i wouldnt put it on my dick." but means more like "i dont care"
person a: "man, your eyes are real red. theyre gonna know"
person b: "whatever bro, gleeris"
