Would be logical if he said "even hurl it on the wall" but it does sound like something beginning with a W, I might be wrong... :)

It isn't very clear, but it sounds to me like he is saying: "Yes! You can wham it on the wall." In this context "wham" would mean to strike something hard. It comes from the sound the strike would make: wham! (Imagine the "wh" sound being the sound of something flying fast through the air, and the "am" as the striking sound.)
