Whiteboard Baiting

When a teacher or adult unintentionally says innuendo to the class whilst giving a lesson, just waiting for a student to yell out "that's what she said" or fall into tears laughing.

Did you have Mr. Harris for physical science this morning?
Yeah. He was whiteboard baiting us for the whole class on friction!

He kept telling us "When you grab something and rub it, you create friction, which radiates heat from the object."
We were trying so hard not to laugh
