Common on hot days, a Sweaty Arse (n.) will usually leave an embarrasing arse shaped mark on a chair which will be obviously pointed out by a Rayfield who wants to get revenge on a Greg.
The "Sweaty Arse-Marker" will feel victimised and thoroughly left out after his unfortunate accident, something which is common in modern Australian society.
Jeebson (thinks): "Oh damn, theres a sweaty arse mark on my chair! Hopefully I can cover this up..."
Floog: "Ahahaha look at Jeebson, he left a sweaty arse mark on his chair! Let's victimise the little Greg!"
Jeebson: "Damn, your such a Rayfield!"
