Morphology

brain + fart

The constituents point in the right direction—'brain' signals something mental and 'fart' evokes a brief, embarrassing emission—so the idea of a brief, silly mental lapse can be metaphorically inferred. However, this is a slangy, culture-bound metaphorical extension rather than a straightforward compositional meaning, so a B1 learner who only knows the literal words may not reliably derive the exact sense without exposure.

Etymology

Brain fart is a slang image that makes a funny picture: your brain has a small fart that makes thinking stop for a moment. One popular image is that this sudden little 'burst' in the head causes you to forget or say something silly, so it means 'a short, embarrassing lapse in memory or concentration'.
