Shit! Now I'm going to have to clean the floor since i overshot the runway.

Be careful not to overshoot the runway onto your laptop.

Overshoot the runway 

To consume significantly more alcohol than planned, to err on the side of excess consumption.

Went out for a couple of pints last night, unfortunately I managed to overshoot the runway so dont expect me at work today.
