One of my favorite jokes as a 7 year old was from Blanca Nieves 
 y los Siete Enanitos. (Snow White and the Seven Dwarfs.) 
 The dwarf in the play said, "the stepmother isn't pretty and she 
 isn't ugly." 
 She's pretty ugly. 
 That's pretty funny when you are 7 years old. I still don't mind 
 the joke 40 years later. 
 Spanish has a similar double usage of one of its common words. 
 If you ask an amigo, 
"¿Cómo estás?" (How
are you?) 
 You'll most likely understand this reply: 
 
Estoy bien, gracias. (I am well, thanks.) 
 That's the old textbook Spanish lesson 101 right there 
 But what if your amigo said, 
 
"Estoy bien mal." 
 Huh! 
 If you translate that literally you end up with, "I am well bad"???
  
 That makes no sense. 
 Here's what's going on. Your amigo just told you, "I am pretty 
 bad" or "I am pretty sick." 
 Yes, like the dwarf joking about 
la madrastra de Blanca Nieves 
 (Snow White's stepmother) being pretty ugly, 
bien, like pretty, 
 has two meanings. 
 
Bien most commonly means 
well but it also means
pretty, 
very 
 or 
quite. 
 
Estoy bien mal, means I am quite/very/pretty sick. 
 Here are some more examples in which 
bien can mean 
 quite/very/pretty. 
 
El Coyote canta bien mal pero me gusta su música. 
 El Coyote sings pretty badly but I like his music 
 
Voy a llegar bien tarde.     
 I am going to (arrive) be quite late. 
 
Esta guitarra tiene un sonido bien Español. 
 This guitar has a very Spanish sound 
 
La cerveza está bien fría. 
 The beer is very cold. 
 By the way, this is not slang. It's even in 
el Diccionario de la 
 Lengua Española de la Real Academia Española. (Spanish 
 Language Dictionary of the Royal Spanish academy.) 
 Bien is just one of many common Spanish words that have 
 extra meanings. These secondary meanings are so common 
 that Spanish Ear Training Master Classes #2, #3, and #4 are 
 dedicated to that very tema (subject).
