Morphology

blow + up

The sense 'become suddenly very popular' is a metaphorical extension of the literal senses of 'blow' (sudden force/expansion/explosion) plus the intensifying particle 'up', so a learner who knows the constituents can likely infer a general idea of rapid increase or spread. However, the social-media nuance (viral sharing/popularity) and the specific usage as a phrasal verb are not fully predictable from the parts alone, so prior exposure helps for the full meaning.

Etymology

Blow up comes from setting off explosives to make things explode, like workers who use charges to blow up rocks to clear a road. That's why it means 'to explode' or make something burst violently.
