Noun. The sound a person makes while giving a great deep-throat blow-job and trying to say "Oh God, I love you.".
Dude, last night I was getting this great blow-job and when she looked up at me, all I could hear was "Ogallala". I didn't want to ask her what she said because she probably would've stopped sucking. I've never been to Nebraska.
