pppooooowwwweeeeerrrr!

That moment when you mash your throttle pedal down in an eco-friendly shopping trolley of a car usually driven by little old ladies, and wait for the burst of power that is simply never going to happen in your current lifetime.

Best shouted in a poor attempt at a Jeremy Clarkson impersonation "Pppooooowwwweeeeerrrr!"
Can often be followed by the 'add-on term' "And speed!"
