well this sucks

When you do something idiotic and you want to curse but there are a bunch of ladies or other people so you decide to tone the cursing down.
Or when you want to be pessimistic but funny.

Sucking Diesel

Restarting a diesel engine e.g. your tractor after it had emptied the tank was very difficult back in the day. There wasn't an electric fuel pump to pump it from the tank. It had to be sucked by the mechanical, engine driven, diesel injector pump. Rather difficult if the engine has no fuel to get going. Once you did get the engine running with out cutting out again you'd know it was finally sucking diesel

Now we're sucking diesel
