Buckhorn Bellow

Screaming your own name as loudly as possible rather than your partner's (or anyone else's) at the height of a primal orgasm for the purpose of both perplexing them and congratulating yourself for a job well done.

Sally: "You won't believe what Dave yelled out while we were having sex last night."
Jane: "Oh no...did he scream another persons name?"
Sally: "No, he Buckhorn Bellowed. Apparently he was proud of his work."
