Mola cacho (MO-lah KAH-cho) – very likeable; mola roughly means that something is likeable, and cacho means “piece” (cacho de pizza = piece of pizza).
Brutal (broo-TAHL) – amazing
Acojonado (ah-ko-ho-NAH-do) – scared
Cantamañanas (kahn-tah-mah-NYAH-nas) – a bullshitter. Used especially for people who say they will do something, but then the never do. It literally means “sings tomorrows” which is a much more poetic way of getting the idea across; I imagine someone singing of what they will do tomorrow, but tomorrow never comes.
Fantasma (fahn-TAS-ma) – this is a similar concept to cantamañanas; someone who is exaggerated, presumptious.
