mung butter
Simply take a good batch of mung, which you can find in any dead bitch, and spread it on some toast and enjoy.
Dame that mung butter was fucking great!
munge butter
The delicious final food product resulting from successfully munging. Must be eaten immediately from the churn to be considered munge butter, otherwise it turns into munge fudge.
Last night me and 3 buddies went munging and they let me have the munge butter.
