Morphology
like + crazy
The sense 'very intensely/quickly' is directly derivable from 'like' used as 'in the manner of' plus 'crazy' meaning 'insanely' or 'extremely', so a learner who knows those words can infer it functions as an intensifier. This simile-based, compositional pattern is common across languages and follows regular English usage (though informal), making it understandable to a B1 learner.
Etymology
Like crazy comes from a simple image: imagine someone acting as if they were crazy, moving wildly and without control. So when you do something 'like crazy', you do it very quickly or with a lot of energy.
