Osterize, (verb) an event in which a participant's head is implanted between a couch/bed cushion after strenuous sexual intercourse. This is usually performed from a doggy style position; however, it is possible to perform an inverted osterize utilizing a missionary position. The term osterize became popular circa 2006 and originated from the ostrich-like features of the recipient after being osterized. Ostriker, (noun) an individual who osterizes.
