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.
When someone has really creative ideas and they won't let their friends alone about it and they go on and on and it becomes an infection that becomes infectious and nobody wants to be around them because they are noxious and obnoxious
