Morphology
like + a + rat + up + a + drainpipe
The expression uses a literal simile: a rat climbing 'up a drainpipe' evokes a rapid, urgent upward escape, so a learner who knows 'rat', 'up' and 'drainpipe' can compose this image and infer hurried movement. This imagery is compositionally transparent (an animal + motion + narrow escape route) and follows familiar simile logic, making the phrase understandable to a B1 learner who knows the constituents.
Etymology
Like a rat up a drainpipe comes from the clear image of a small rat running straight up a narrow drainpipe to get away. That fast, sudden climb is why the phrase now means 'very quickly' or 'in a great hurry', especially when someone is leaving or escaping.
