look up any word, like the eiffel tower:
 
1.
The act of smashing a mushroom on someone's head. You have to sneak up reeeeally careful and sneaky, and then scream "You just got SHROOMED!" As soon as you smoosh the mushroom.
Some one, let's say Bob, sneaks up behind Fagan, and, bringing the mushroom down on Fagan's head, Bob yells "YOU JUST GOT SHROOMED!!!"
