Cabronauta
It comes from the Puerto Rican slang technically meaning “Un cabron perdido en el espacio. Literalmente alguien que se distrae y se pierde de la realidad, en un viaje”. Translated a cabronauta is that one friend that zones out to such a level that transcends him beyond space.
Hey Bob, you seen mark lately? Yeah man the cabronauta is right there, it’s just that he’s so zoned out it’s like he’s not even here. / Spanish variant: Este Carlos es todo un cabronauta, uno le habla y el muy mamon ni responde.
