But the examples given by my dictionary seem different: a comparison is spelled out:
metaphor
n.
Fr m=taphore < L metaphora < Gr < metapherein, to carry over < meta, over (see META3) + pherein, to BEAR16 a figure of speech containing an implied comparison, in which a word or phrase ordinarily and primarily used of one thing is applied to another (Ex.: the curtain of night, “all the world‘s a stage”): cf. SIMILE, MIXED METAPHOR
met#a[phor$ic or met#a[phor$i[cal
adj.
met#a[phor$i[cal[ly
adv.

But when I looked at Metaphors in the new site, it gave examples that DO fit:

"Did you land a job today?" "No, not a bite".
