Anything from Gears of War 2. Absolutely anything. Not awkward in the sense that its suggestive, more awkward in the sense that every line spoken has you looking down at your feet because you geniunely feel embarrassed for the voice actors.
Although, come to think of it, it can actually be pretty suggestive too. Most of the conversation between Phoenix and Dom has the "I want you inside of me!" subtext, except its about as subtle as a sledgehammer to the kneecap. Big manly men, running around having adventures while making a (frankly half-hearted) attempt to search for one of their wives, and admiring each other's muscles, whilst talking endlessly about how manly they are. Suspiciously specific denial, amirite?
