Right Hand Side - RHS

Where you drive in the U.S. (don't try it in Britain...you'll get a lot of honks and rude gestures). Or...where you should wear your pistol if you're a right-handed gunslinger (cross draws are for the movies).

It's also an expression that comes up in currency pricing. When currencies trade, the bid/ask spread for their prices gets listed something like this: for GBP/USD, 1.2630/1.2640. In that structure, the right hand side (or RHS) represents the "1.2630." It's the offer price for the currency pair...the price at which you can buy the British pound or sell the U.S. dollar.
