Pharsal verbs

This is a topic that I like, since these phrasal verbs are very useful, in addition to being combinations of other verbs, their meaning changes and for this reason I consider them very useful, apart from that are very used by the Anglo culture.
Some of them are:

A

Answer back- replicar, contestar protestando

Ask out- invitar a salir 

Ask over- invitar a tu casa 

B
Back down - echarse para atrás en una decisión que provoca enfrentamiento
Back off - retirarse, alejarse, evitar
