A phenomena that occurs when a man experiences sudden uncontrollable joy. This can be brought on by a variety of circumstances - all of which depend on food preference, likes/dislikes, and/or sexual orientation.
The "manty puddle" can range from a small quarter sized stain on the front of the man's pants (caused by the release of Cowper's fluid) to an entirely soaked leg (due urinary incontinence).

Husband: "Wow honey, would ya look at the blade on that circular saw! Can you imagine all the wood I could cut with that?"
Wife: "Would you mind telling the wood in your pants to settle down?! Are you developing a manty puddle darling?"

Bro 1: "Dude, did you see that top that Janice is wearing tonight? Those sweater puppies look like they could use some air. I'm gonna see if she'll let em out of the cage tonight!"
Bro 2: "Slow down turbo...you need to check your front deck. Is that Guinness on your grundle or did you just acquire a massive manty puddle from staring at Janice?!"
