Hey.
Girl: Hey.
Damn, I forgot my spray bottle.
Girl: What?
It says "spray on flat surfaces."
Spray On Flat Surfaces
Explanation
Explain Bear
Listen up, buttercup. The joke plays on the double meaning of "flat." One meaning refers to smooth surfaces, the other refers to a woman's chest. The dude is implying the woman's chest is flat and he needs the spray bottle to spray on flat surfaces.
