Quite possibly the coolest non-profane exclamation there is.
Its got the powerful "What the -"
with the added on "Junk!"
("Junk" on its own can be used as an interjection.)
And the best part? "What the Junk?" comes with free refills. So you can Wtj all day long for frizzle.
RiQ - D00d, What the Junk? That meteor smash was soo cheap! uber-fail!
Noah - lol, how do you like my leetsauce?
A gentler way of saying "what the F***." You say this becase A)you're around little kids B)it just sounds funnier.
Steph: What the junk did I do with my hat?
