Similar to a 'Prelash', this activity involves intoxicating oneself with the Green at home as a precursor to the night's excess of tokin' on someone else's Hash. Essentially, it's a way to get the party started before you even get there!
"Ey man you comin' to my shed tonight, gonna have some weed on me boy."

"Sure thing dude, just gonna have a Prehash at home"
