Put the cash in the safe and here's a extra slug 'fore I shake
You smoke faster than me with a eighth

from TDE (Ft. Ab-Soul, Isaiah Rashad, Jay Rock, Kendrick Lamar & ScHoolboy Q) – BET Cypher 2013 Lyrics on Rap Genius

Meaning

To shake is to leave the area and shake is what you call whatever is left after the bud of weed is broken down. Clever wordplay with shake/smoke/eighth, you’ll get smoked faster than Q smokes an eighth of weed
