Morphology

lamebrain + moment

The meaning 'an instance of foolishness' is directly and compositionally derived from 'lamebrain' (someone foolish) + 'moment' (a short time) — i.e., a short time of behaving like a lamebrain. This simple nominal modification/compounding pattern is common and transparent, so a B1 learner who knows both constituents would readily infer the MWE meaning.

Etymology

The phrase lamebrain moment may come from the old use of lame to mean 'weak' or 'not working' combined with brain, so it paints the picture of your brain not working for a short time. That's why a lamebrain moment means a brief time when you do something silly or forget something.
