A variation of cunnilingus where you keep your tongue straight and hard like steel while she plays your head like a drum.
Me: Man, I had a strange experience last night while hooking up with that girl. Freddy: What happened? Me: As I was going down on her she started to play my head like a drum and told me to stiffen my tongue?! Freddy: Sounds like she loves to play the steel tongue drum!
