Danger Dunk
The act of performing a high risk maneuver which involves dunking a biscuit in tea for a recklessly excessive period of time, resulting in a structural failure of the biscuit. This causes an undesirable sodden residue in the bottom of the cup which may be accidentally ingested, causing you to reconsider your life choices.
