The basic manly instincts that every guy is born with. Such as being able to drive well or navigate through anything without asking directions.
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.
Since he is immature, his manstincts are not (yet) fully-developed. Every new father needs to learn to trust his manstincts (in the same way a new mother needs to trust her woman's intuition). My manstincts went haywire when I heard that lame suggestion.
