A vapid man with little to offer in the way intellectuality or adventure. Figuratively speaking, the guy has but two thoughts: sex and sandwiches. Mainly exhibited in male-female relationships when the woman is talking about important topics or in social situations where sports, cars, sex, or food is not being discussed.
Woman: I really feel we need to communicate more.
Sandwich Guy: <I can still taste that ham cheese>
Woman: I feel like you don't listen me.
Sandwich Guy: <Listening = Sex>
Woman: Thank you for not interrupting me, I really need to get this off my chest.
Sandwich Guy: <She said chest haha. We're banging soon!>
Sandwich Guy: Time to undress!
