írsele el baifo (impersonal, third-person singular present se le va el baifo, third-person singular preterite se le fue el baifo, past participle le ido el baifo) (Canary Islands)

1. to forget what one was going to say, to lose one's train of thought
2. to say something one doesn't want to or shouldn't say

The pronoun le serves the function of indirect object, and thus can be replaced by the dative case of any personal pronoun, e.g.: se me va el baifo, se te va el baifo, se nos va el baifo, etc.
