In the days of sail, naval vessels mounted cannon carefully and purposefully rigged into positions which optimised the effect of their fire. Occasionally, the rigging of these very heavy guns might come loose, and with the vessel pitching about on high seas or during manuever in battle, the results for the ship and crew could prove catastrophic. The term has come to describe a person lacking prudence or insight, whose actions and/or speech jeopardises the safety of people in their proximity or under their authority.

A drinking game in which the participants consume Haribo fat-free gummy bears before trying to attain the contact information of an attractive member of the opposite gender. Due to the explosive effects that the gummy bears impart on the participants bowels, this means that the attempt to attain information is under a very strict clock. If the participant attains correct information before expelling the contents of his bowels then all of his / her comrades must drink, otherwise he must.
