The phrase "milk DUD" is a lesser known term for bro, because of bros pronunciation of the word "Dude". The bros are so over-whelmed with their broness, they feel the need to pronounce the word "Dude" like the word "Dud", we get "milk DUD" because it just sounds like it makes sense.
The feeling one gets after attempting to carefully pour milk into a cup and yet having milk uncontrollably dribble onto the counter, even after years of practice.
Anne: Wow, what's the matter with you this morning?
Quite a rare speciment indeed! When one sticks a straw up a girls vaginal area and sucks all the liquid out! IT is very done correctly, but when done by the masters it will give the girl a tingly feeling!
