Plural of daff; informal term for daffodils or silly/eccentric people.
Either a shortened plural of 'daffodil' or plural of 'daff' (a silly person), from the adjective daffy or the verb daff (to joke).
English speakers love shortening flower names for casual speech—'daffs' for daffodils works just like we say 'mums' for chrysanthemums or 'dahlias' informally, creating a cozier, friendlier way to talk about spring gardens.
