A well known Australian statement first made in January 1992 by Western Australian Cricketer 'Frank Halliwell' towards international cricketer 'Tom Moody' during a cricket game at the WACA stadium. Tom stated, "he wont be out here long" and was replied to by Frank "Youve been sniffing too much glue mate" (resulting in a huge response of laughter from players, members of the WACA and those in the crowd including Tom himself)
The following 6 ball over, Halliwell smashed Moody for 4 sixes, with the 5th ball being hit out of the top of the WACA stadium (over the Dennis Lillie stand onto the street into a Police vehicles side window) and is now recorded as one of the largest 6s ever hit in the world during an official WACA/ACB (now Cricket Australia) cricket competition match. Toms #6 ball was hit for a 4 runs. Tom congradulated Frank after the match with a handshake and a beer.

When a roadman (preferably over lvl 203) says you have got some nice or “peng” shoes or “creps”

It mean "You have", but when you talking about something expensive.
