Weed Bro's Mother is the unnamed, seldom-seen mother of Weed Bro. She is extremely physically and emotionally abusive, and once beat her husband for thirty minutes straight for having romantic relationships prior to having met her. Weed Bro does not seem to take issue with this behavior. Her favored weapon is the flip flop.
In a later comic she is revealed to have been one of Sarcastic Bro's teacher. It is presumed she resigned.
Her violent tendencies are only matched by her tremendous throwing ability. The weight of the average sandal is just a little over one pound, or 16 ounces. The weight of a baseball is 5.25 ounces. By throwing the sandal at 120 km/h. In comparison, the world's fastest car, the Hennessey Venom GT can travel at 435.31 km/h. The average car travels at 65 miles per hour, or 104 km/h. The fastest baseball pitch is 169.14 km/h, thrown by Aroldis Chapman. The average pitching speed for professional MLB pitchers is 148.06 km/h. The average person can pitch at 96.5 km/h. Therefore, if a baseball weighs three times as less as the sandal, she could theoretically pitch a baseball three times faster. This would be 360 km/h, which would mean a pitch from Weed Bro's Mother would travel three times faster than the average car, and nearly as fast as the fastest car ever manufactured.
Weed Bro's Mother has likely let her son play too much GTA. Weed Bro's Mother is likely innocent when it comes to sexual innuendos, as seen from a tweet from her complaining about 'yogurt' constantly spilling over Weed Bro's pants, with the implication that the yogurt is likely semen.
