A man's gotta eat
A man's gotta eat is what your friend says when he knows he's with a girl who's not hot, not smart, and might have a bit of a belly.
My buddy said, 'A man's gotta eat,' after he spent the night with his cousin.
He texted me, 'A man's gotta eat,' right after he kissed her.
He said it again when he saw her eat a whole pizza.
