An erection at a awkward moment, usually a business meeting where ladies are present.

Often noticed when you stand up and shake the lady in questions hand.

Usually an attempt is made to hide it by arcing the back at a 45 degree angle and shuffling out the room.
e.g.

I'm not sure we got that deal mate, Phil was nursing a boardroom banana all the way through.
