It is a
Portuguese expression, translated to "desenmerda-te!", that is used when you want to
say to someone that they're stuck in the
mud and they need to sort their stuff out.
Nao ha comboio hoje? Vens a pe! Desenmerda-te!
Tens de ca vir ter - Is there no trains today? Come on
foot! Unshit yourself. you've got to come here!
