Deadpool travels back in time to April 1889 to kill baby-Hitler. He enters the nursery and sees him: Boy howdy. Hi. This is a toughie. Yeesh.

I don't quite understand what "boy howdy" means here. Does it mean "Well, hello, boy"?

    “Boy howdy” is another Southernism, usually attributed to Texas and evidently popular in that state. It’s a simple combination of the exclamation “Boy!” (indicating surprise) and our friend “Howdy,” together used to mean “Wow!” or to indicate strong agreement with a statement or question.
