Yes, I vaguely remember that the Hondurans are nicknamed the 'catrachos' and the Salvadorans are nicknamed the 'guanacos.' These nicknames are indicative of the existing rivalries between the two nations, although on another level it is sometimes not clear whether that is a national thing or a matter of the various tribal groups that are always migrating hither and thither, which is not so easy for white people to notice, at least not at first glance. Sometimes the borders of a country mean something different than what they formerly meant, before the migrations of the tribal populations, someone was trying to say, but even so, the borders are what they are for administrative purposes.
So does that make the Honduran catrachos necessarily catty?
And why should the Salvadorans be called guanacos, an animal similar to a llama but smaller, that lives only in South America, mostly Argentina? Does that make the rival Chileans necessarily Catrachos? But that would not make any sense, as the catracho nickname was bestowed upon the Hondurans by the Nicaraguans, and Nicaragua was invaded by Walker, not the Chileans, although who knows what Chilean soldiers of fortune might have played a role in the Central American military conflicts of the 19th century.
So these matters are not going to be foremost on the minds of most Americans such as myself. Needless to say.
