Someone, female or male, who says hi to you one day, then the next acts like he or she does not know you.

This usually happens because that person(the streaky dapper) is stuck up, and only says hi to you when they want something, like attention.
"damn, that girl is a streaky dapper..yesterday she was like "heyyy" and today she acted like she didnt even see me..
