Kat Smith's definitions
When you have no time, are unprepared, or don't know what you're doing...  You're pulling it out of your ass.  Commonly used in situations where a person may have procrastinated or waited until the last minute to prepare anything, or is put in position where they must perform or answer questions on things they have no idea about.
