Person 1: "You've been staring at that screen for an hour, and haven't done a thing. You know this work's due in an hour right?"

Person 2: "Yeah, I got like four hours sleep and can't concentrate. It's definitely caffeine o'clock."

Approximately half an hour after caffeine o'clock, at which point a visit to the bathroom is commonly required.

Often a forgotten consequence of caffeine o'clock, half past caffeine tends to become pressingly apparent to the victim at a most inconvenient time.
Supervisor: Where do you think you're going? You just had your coffee break half an hour ago!

Victim: Yes, which makes it half past caffeine! Oh god!

A car produced by Holden (Australian division of General Motors) and Isuzu from 1975. This car was also sold in Japan, America and Europe, as the Gemini, Imark and Kadett respectively. Rear wheel drive (real) models (TX,TC,TD,TE,TF,TG) stopped in Australia in 1985, and were followed on by a front-wheel-drive which noone really cares about, called the RB. This model was, however, sold in limited turbo editions in some countries.

The rear-wheel-drive Gemini was generally powered by a 1.6L 4 cylinder sohc carburettor engine backed by a 4 or 5 speed manual, or a rarer automatic gearbox. A ZZ/R special edition model was released in sedan and coupe featuring different styling, an LSD diff, and a far more advanced 1.8L twincam EFI Isuzu engine called the G180W. Other engines which can be bolted in include 1.8L and 2L versions of the original 1.6L (G161z, G180Z, G200Z) and a 2L version of the twincam, called the G200W.

Modifications to the base Gemini models tend to include weber carburetters, performance cams, new exhaust systems, mag wheels, new suspension, etc. Whilst starting as a fairly low powered car, they feature rear wheel drive and a kerb weight of just over 900kg, and have therefore a lot of potential for being very fast and fun cars.
