"Solo mate" as in No way!
Solo mate (no accent presented) can mean You like it? or Seriously? No way! according to a Nicaraguan friend. Anyone know this phrase? I am wondering how this phrase comes about. The only thing I pick up on this is a preterite form of matar, but it doesn't make any sense to me.

Looks it you're on track and in this case it has nothing to do with Mate from Argentina.
It isn't much, but this confirms what your friend told you. As for the origin of the phrase, good luck.
Bueno el Mate es una bebida popular en Latinoamérica 
Si no es eso o el verbo matar no se a que se puede referir a no ser que se trate de una expresión que usen allí
Como dice Neox, probablemente sea la bebida, pero tenemos también la frase 'Jaque -mate' en ajedrez. Checkmate??
