Term used to 'covertly' communicate one's opinion on the attractivenss of another human being, a roundabout phrasing of "smash". Can be used in many circumstances, as part of a sentence or as a stand-alone exclamation. Partciularly useful in the presence of girlfriends/wives and preferable to "I'd plow that into the ground".
Silent 'h' is preferable to achieve the desired effect, leaving the sound of 'Sam-ash'

Girlfriend: "What???"
John: "Just remembered someone's name from work."
2. Guy 1: "Would Sam-Hash. Defintiely Sam-hash."
Guy 2: "Smashtastic. A solid smash out of smash"
