Get the Slugfuck mug.
A general state of chaos or disarray. Similar to clusterfuck.

Etymology:

The ancient British originally used the word 'fuckslug' in situations where the word 'fuckton' was too hyperbolic and generally just over the top. With a decline in the use of slugs as a mass unit, the seventeenth century saw a reversal of the word into 'slugfuck', and a further evolution of its meaning to the current usage.
Rob: Wait a second - is it ton, tonne, or tun? God, this whole system is a complete slugfuck.

Steve: I know. Fucking brits.

Rebecca: Seriously.
