What Does "¿Qué hace?" Mean?
¿Qué hace? is the way to ask what a third person (he, she, it) or second person (you) does or is doing.
¿Qué hace? is often used as a funny way to greet someone in phrases like Hola, ¿qué hace? ¿Durmiendo o qué hace? (Literally Hey, what're you doing? Sleeping or what're you doing?).
You'll also see this phrase in memes featuring a llama asking questions like that shown above, although with incorrect spelling and punctuation: Ola k ase? Durmiendo o k ase? Much like LOLcats, apparently the Llama ola k ase (the Ola K Ase Llama) doesn't know how to spell.
