A brat (Bratwurst; dick) that has been placed in a class of beer for 15 minutes or more

His girl then performs a Full Service Lube Job; he asks her if she tasted anything different; he then hands her the glass of beer that marinated his dick so that she can wash down any remaining cum in her mouth
When MOCO performs a Beer Marinated Brat, he likes to use Stella Artois; US beers aren't classy enough for such a job!
