Morphology

turtle + up

The phrase evokes the turtle's literal behaviour (withdrawing into its shell) and the particle 'up' adds a sense of closing off or retreat, so a learner who knows 'turtle' (as the animal) and 'up' could plausibly infer 'withdraw/retreat'. However, this is a metaphorical verbing of a noun and not a fully regular phrasal-verb pattern, so the mapping is suggestive but not entirely predictable without exposure.

Etymology

The phrasal verb turtle up may come from the image of a turtle pulling its head and legs into its shell when it feels scared. That's why turtle up means to pull away from people or feelings, to 'withdraw' or 'retreat'.
