look up any word, like sex:
 
1.
To sandbrook or sandbrooking is the act of defecating in one's hand, rubbing it across their forehead, and proceeding to sing bohemian rhapsody whilst running around in a public venue, preferably a Micheal's craft store or Jo-Ann's Fabrics.
"What happened to Kenny?" "Ah dude he totally sandbrooked last night and is in jail now"
