"I am not going to miss!" said the boy swinging at the pinata. Does perder also mean "to miss"? UPDATE: A Hispanic friend just used PERDER in conversation as to forget. I checked the dictionary and that is the third definition of the term, but he said it is used a lot with that meaning. So, "miss" in the sense of "forget"... Not exactly the piñata I was swinging at last year with my comment.
The poster above doesn't appear to be active anymore. It would be nice if he/she had given an example sentence. The best I could find is that in some countries the verb abanicar can be used in baseball as to miss hitting the ball. But abanicar generally means 'to fan'.
The lack of an object is the reason why it can't be "miss." "Perder" doesn't mean "miss" as in swinging and missing or missing a target with an arrow. It can only mean "miss" in the sense of missing a train or a plane or something like that. It can also mean someone doesn't "miss a trick" to borrow an English idiom. And we would normally say "I'm not going to miss it" if we were talking about missing a class or missing a plane (ie. not showing up for a class or being late for a plane). So you would need an object in this sentence in order for it to mean "miss."
It's also a very rare meaning for "perder," which nine times out of ten (or more), means "lose" or something similar
ngmuipai asked the question would the use of perder meaning to get lost, would it have to be reflective. Mavey (native Spanish speaker said yes and gave an example. The model sentence is not in the reflective mode so it cannot mean to get lost.
However when perder is used in the intransitive mode with no objects, it means to lose as in losing a ball game etc. The model sentence is in the phrasal future which is known as 'ir+a+infinitive. So it translates to I am not going to lose. Hope this helps.
