"Yo, bro, how much can you pay for this item. I want 70%".
"Sorry the best I can pay is 60%"
"Ahhh, don't do a Harrow on me!
The 1% less version of Eton, but it’s cool cos they do have those Toffed up boaters.
Harrow boy: what are you doing here Eton Boy?
Eton boy: dominating in cricket obviously chap
Harrow boy: shut your gob before I turn you into an Eton mess oldboy
Usually, an annoying old white man who goes to Egypt to resurrect a psychotic crocodile god because he has a domination kink
