The act of rolling oneself tightly in a blanket so as to resemble the Pokémon Metapod. Used to gain warmth or to immobilize oneself in preparation for evolution.
My heater broke last night and it was freezing in my bedroom. I was metapodding trying to gain some warmth.

Jessie was so tired after a day at school that she metapodded and took a nap.

Brandon: Hey dude my its so cold, i would say i have bullet nipples but they are so hard they are metapoding.
Carlos: I know right.
