when one has the inability to speak or function because all of the blood has rushed out of their head to their boner. generally makes the affected person very stupid for the duration of the boner. mainly occurs to men with large schlongs.

When your boner takes over thinking for your brain. Similar to the Blood-Brain Barrier where only certain substances can pass through to the brain. The Boner-Brain Barrier doesn't allow any thoughts to be processed from the brain since they are all processed from the highly sophisticated thinking center of the penis. This can result in making illogical decisions and having regrettable sexual experiences.

Something that strikes a chord in someone's thinking, creating a spur of "enlightenment" and stimulation in knowledge, especially in subjects like philosophy & logic.

The feeling you get when you are having a lively discussion or listening to an engaging lecture and everything makes sense and it gives you a bunch of new ideas about the topic at hand. The intellectual equivalent of an erection.

When you are so intellectually stimulated your brain gets a boner.
