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!"

when you discriminate/dehumanise dumb people.
eg when you realise that u have literally no chances of being anything successful bc ppl only want smart ppl in jobs >:(
like where r my dumb lawyers?? dumb bankers??? dumb engineers?? ppl like to say that smart ppl make the world go round. that is incorrect. without dumb ppl there would be no humor we would have a soulless world. dumb ppl tend to be less egotistical, which is cool ig.
