When your female sexual partner is menstruating (with consent). you collect her mensuration discharge in a cup, containment vessel or condom then mix in as many cum loads as you can muster. Presto you have yourself a Milwaukee Milkshake,Perfect to wash down a hearty meal.
"Hey babe, that Milwaukee milkshake we made the other night do you think it'll still be good? It's been in the fridge..."
Utility beer is the beer you keep around for the day-to-day moments when beer is a necessity to assist in pedestrian activities (golf, plumbing, yardwork, babysitting, staff meetings, Zoom calls). For the beer snob it is the beer you save for neighbors when they drop in at 3 p.m. on a Tuesday. It is differentiated from the actual high-end beer you save for special events, holidays, and special tastings.
Person 1: Dave, did you bring along those hazy craft IPA's so we could drink while cleaning Lyle'spool?
Person 2: Nope. I just have a bunch of utility beer that Steve dumped on me. Good enough for this. It is only 10:30 a.m.
