After drinking that case of cheap .99 cent labatt ice mixed with old english malt liquor i've become a master at supressing my gag reflex whilst at the same time managing to get pissy drunk for a measly 4 dollars! a win win!
The natural urge to vomit when a large, oversized object is inserted into the throat. This is either purposefully suppressed by a person, or occurs as a side effect of having ones tonsils removed. Considered by men to be a highly desirable trait for a woman to lack. See also deep throat and face fuck.
Since I have no gag reflex, I let him slide his whole 12" down my throat!
