I was going to answer Yngwie Malmsteem

But actually, I realised that the both of them are actually masturbating while GUITARING

I'd say playing air guitar in front of a mirror is close to getting caught masturbating. Which I've done many a time.

[quote and make fun of]

Can't be worse than masturbating infront of a mirror; it shouldn't be done; it's the first commandment in the Wanker's Bible.

Not to mention the smudges.

I reccomend Windowlene.

I've been caught both air-guitaring and bashing the bishop, and I have to say it was a lot worse when my old man caught me with my trousers round my ankles.

Bashing the bishop?! ha ha! What did you're old man say?, I can imagine if my dad caught me in the act it would just never be spoken of again...

Haha, at the time he just said 'sorry' and quietly left the room. I could of died basically.

It's my second tic, I can't help but doing it. I do it in public, I really don't care.
My first one is air drumming.

I think both are fine. Although at least with masturbating there's a decent cue to walk out. You catch someone air guitaring and you're obliged to either make conversation or join in, which can be really embarassing.

Group air-guitaring = soggy biscuit circle jerk?

I think being caught replying to this thread is worse than both.

But that ain't got nothing to do with a good time.

I'm really bad to strum and make notes/chord shapes as I walk. I can't help it.

there's air guitar and then there's air guitar.

masturbation is always masturbation.

I feel like if I could play guitar as well as I air-guitar, I'd be famous by now.

I feel I could masturbate and play air-guitar at the same time.

Are you talking about air guitar or masturbation? It changes the meaning of your sentence a lot :D
