a) To be caught masturbating
b) To masturbate
I thought my roommate was out of town, but he came back in the room and totally metcalfed me.
I am going to metcalfe until I can’t walk no more!
Another word preferable to the more immature "Dirt Road" term.
Is a reference to poop stuck on your anal hairs.
-Oh dear, I can't crap due to the immense metcalfing of my anal region.
-Oh shit, I forgot to wipe my bum properly and now sport a massive metcalfe.
