Similar to the actual phrase "Nostalgic", Nostaldick refers to a dick you haven't taken in years.

Noun. Obvious portmanteau of "nostalgic" and "dick". Someone who is stuck in the past and refuses to get with the times.

The female version is "nostalclit".
Shipley's donuts has a $5 minimum for credit cards. They are clearly enticing you to pay in cash as if we live in the 1900s. What a bunch of nostaldicks.
