Boardwalk

[Lizzy Liz]

As in [monopoly], something or someone that is seemingly [unattainable] but yet very desirable. Whether this is due to not being able to read or understand the person or object or whether the person or object is just too weird and indescribable (not to mention confusing and somewhat frustrating). If the thing you are describing is a person, it is someone who constantly surprises you and you are unable to rely on them due to their constant changes in behavior and attitude toward you. This also means you can go from loving them to hating them in a matter of seconds. If the thing you are describing is an object it is something that you cannot figure out its purpose or [necessity] to ever being invented.
