Tap on the glass
Can mean two things. A hearty clink of two bottles being knocked together orrrrr... when your x boy friend comes to your work... preferably a school and starts tapping on the glass making the children feel like they are about to be shot dead (this is in America by the way) and the teacher as though she is about to be obstructed.
Wow... what a tap on the glass
