The act of vigorously masturbating penis, aided by either poppers, weed, or both and often at the expense of personal relationships and productivity. So named because the masturbator engaging in the monkeybate is often so overwhelmed with pleasure that they screw up their faces in a way that mimics a baboon, gorilla, or monkey.
Just like monkeybars, you hold onto one bar before grabbing the next. The Monkeybar Effect is the same only with a woman who will keep her man only until she finds another man of equal or superior quality.
