@Robusto I actually don’t know. It doesn’t really go together, but they say it.
Anda is a second person imperative, and
le is a third person dative (usually). But you can’t go him anything. The reflexive commands going with
andarse should be
ándate (tú) or
ándese (Vd). Maybe they’re actually saying
ándele, although that still leaves me at a loss for assigning the pronoun.
Wiktionary doesn’t explain it either.
