look up any word, like cunt:
 
1.
Reserved, but secretly outgoing deep inside.
Ex 1: She seemed shy, but after talking to her I found out she was crevacious- always the first one to crack a rude/crude joke, moshing like it's nothing, and graffiting anything if it stays still long enough

Ex 2: The young girl sat in the corner of the room, silently wishing she could outgrow her crevacious disposition and finally prove that she could make a name for herself.
