bum tap 

To put simply the quick tapping of another blokes arse in a non-sexual way, often used as friendship/masculinity building, the bum tap is a common trope in senior rugby normally used to congratulate a successful play, a ploy to encourage one's teammate/ get someone moving or as an introductory action to a conversation.

Successful attempts may be met with such responses as
"Good contact!"
"Solid Hit!"
"How are we boys" -(When introducing oneself)
"BOOM"
"G UP MATE"

Attempts may be as hard as the user intends however too soft of a hit may throw the tapper's sexuality into question, or create direly awkward situations.

The Golden Rule however is, Do. Not. Hold. Ever.
No matter what. Nor squeeze.

Bloke 1: "Man Dougan's such a queer kent"
Bloke 2: "Why's that?"
Bloke 1: "On the pitch he gave a bum tap, and held!"
Bloke 2: "The fuck mate, that is not alright"
Bloke 1:"Ay"

Ricky Ponting Bum Tap 

The 'Ricky Ponting Bum Tap', aka the ‘RPBT’ is the only known male heterosexual contact with the arse of another heterosexual male currently in existence - introduced by world class cricketer Ricky Ponting himself. The RPBT consists of between 1 and 3 taps or smacking actions to the posterior of one’s counterpart and/or compatriot (of the same sex). This contact rule MUST be strictly adhered to, as any more than 3 taps to the rectal area of another male may cause questions to arise about the sexuality of the tapper carrying out the act.

Papabear - “What a fantastic shot Casper at the game of billiards we are currently playing! Let us celebrate your most impossible shot by employing the act of the ‘Ricky Ponting Bum Tap’, also known as the RPBT, so as to emphasise our masculinity, heterosexuality, and alphaness.”
