This expression refers to a past situation, decision, or action that can have repercussions which cause problems for somebody in the present or future. Often when these consequences eventually manifest themselves, it is too late to do anything about them. It is therefore often associated with regret. The term is common in both a social and professional context and is similar to the slang expression 'come back to bite you in the ass.'
