in deep water
Meaning
In serious trouble or a difficult situation, often with potential consequences.
Origin
From the literal danger of being in water too deep to stand in—risking drowning. The metaphor extends to being overwhelmed by problems or consequences; it has been used in English for centuries.
Notes
Stronger than just “in trouble”; suggests serious difficulty and possible consequences. Used in speech and writing; often appears as “in deep water with [someone/authority]”.
