Get the Dumb beechmug. When a girl experiences her brain progressively shutting down or feeling foggier with every pump of a penis during sex. The intense physical sensation overwhelms her mind, leaving her temporarily dazed and mentally blank.
"By the third round, I was so pump dumb I couldn’t even remember how to spell my own name. I just laid there, smiling like an idiot!"
