look up any word, like hipster:
 
1.
A guy who is physically ripped and massively hung with giant balls. They can cum many times producing huge loads. Many will drip precum almost non stop. For these reasons they tend to be in the service of cockfed individuals.
1. Jenna was so happy with the new milkbull her parents hired for her, he was hot, cute and tasted incredible. He fed her 4 huge loads and his enormous cock was still hard and throbbing, dripping cum non-stop.

2. Dane had been one of Kerry's Milkbulls for a few years before moving away. But he found her two younger jocks to replace him in feeding her bullmilk.
