look up any word, like blumpkin:
adj: 1. That which is favored by Selleck. Tom Selleck. 2. Of or having an earthy musk.
1. High fives and indomitable mustaches, two of the most Selleckian pursuits.

2. Magnum condoms derive their name from Selleck's self titled character and are therefore considered to be Selleckian entities.
