Superstar Tradesman 

Made popular through the song "Superstar Tradesman" by the Scottish band The View, a Superstar Tradesman is one of the less than bright or unruly kids who left school at 16 to become an electrician/plumber/mechanic. Now earning more money than people of equal I.Q who left school and work in call centres, he gets drunk and coked out his head every Friday and Saturday night at his local, ALWAYS stands at the bar,talks loudly and wears those brown boots that you can't seem to buy in shops. Liable to kick off at any point.

"That cunt who was in our year just bought me and 6 other guys at the bar a round of shots, must be doing not bad for himself." "Yeah. Thick as shit though. Superstar Tradesman."

tradesman trombone 

Whilst not overly musical, the instrument has the ability to arouse an otherwise unmotivated worker to their feet.

Tradesman #1 - I don’t reckon keith is going to make it through to smoko, he was hittin the jars something fierce last night.
Tradesman #2 - Get him playing a few tones on the tradesman trombone and he’ll be right as purple rain.

Poaching The Tradesman's Entrance 

Stimulating your partner's anus, with fingers and tongue before penetration; licking and teasing the anus in anticipation of penetrating; the act of penetrating the anus as part of foreplay. The act of finger or tongue fucking the anus.

She never expected me to poach the tradesman's entrance but she's glad I did: she like's to know I'll be poaching the tradesman's entrance tonight.
