look up any word, like bae:
 
1.
When two men whip their cocks at eachother in an attempt to smash their meat together.
Mike tried to do a Milk Masher on Dylan but it was September, and so Dylan turned him down.

The two men at the cock fights tried to do a Milk Masher to make a super chicken but they ended up making the roosters twitch in pain.
