When one's lap becomes over crowded with random things from multitasking while sitting in same spot for extended period of time.

Derived from the word tidy and lap

After cramming for my art project 's final assignment last night, I ended up with lapuntidus. Took me nearly 5 minutes to clear everything off my lap and around my chair before I could even stand up.
