Man 1: dude how did you get so good at driving?.... you just got your license yesterday.
Man 2: I dont know it must just be my manstincts.

The inner sense of right and wrong for the human post-adolescent male; the adult human male and/or masculine equivalent of woman's intuition (in the singular form) and women's intuition (in the plural form); masculine conscience and/or psyche.
