sneaky maintenance 

Sneaky Maintenance: Somewhat analogous to high maintenance; with the exception that the unsuspecting boyfriend doesn't perceive the maintenance level of the newly anointed girlfriend. Thinking said girlfriend is low maintenance, but in reality, a shockingly high amount of money and time is spent on jewelry, hair, make-up, and clothes.

Kevin thought Ivonne was a low maintenance girl with her down to earth sensibilities and sweet dispositions. The sneaky maintenance side was identified when a 5$ piece of jewelry quickly turned into a $5,000 piece of jewelry. Further identification of sneaky maintenance was realized when the 10 minute “getting ready” time slowly morphed into 1 and half hour getting ready time; which include multiple outfit changes and extensive make-up applications and hair styling.
