Wedding Tackle Defined
Presumably of Australian origin, wedding tackle refers to the male genitals, especially with regards to the genital's mate-luring capabilities.

In Sydney, Australia this week, Andrew Quah, a member of the Family First Party, was fired after he allegedly got blitzed and sent an email to a student-organization list with a picture attached of him flashing his penis. The email stated:

deer left,

u can all go n suck my fat asian cock

hate you,

andrew quah

future src president

also bring me more burbon i ran out

As The Register reports:

Attached to the email were three photographs, all of which appear to feature his wedding tackle, and one of which "shows him exposing his private parts as he takes a picture of himself in a mirror", as the Sydney Morning Herald puts it. Quah told the Sunday Herald Sun - which broke the story - it was "possible that he had posed for the compromising photographs", adding: "I might have been drunk off my face or my political enemies might have drugged me.

Honestly, I just think that wedding tackle is one of the most amusing slang terms for penis that I've ever run across.  And, apparently, this phrase is so common on the other side of the ocean that there is even a British farce named after it, starring James Purefoy.
