This is Donald, and Danald.
These nice boys live down in San Leon, Texas in a sweet tricked out double-wide that they have made into a wood-paneled palace...a shrine dedicated to KISS, and small caliber handguns. Donny (the alpha-twin, with the Peter Criss tat, and bitchin' new jeans) is the wild one of the family, evidenced by his earring ("Only the left ear, I ain't a gay!") and the fact that he got all of his tattoos first. Then shiftless Danny decided to sell his beltbuckle, and bite Donny's rhymes, but got Gene, and KISS in red, just to mix it up a little.
They say you should never judge a book by the cover, and Shake and Bake here are no exception. Donny graduated first in his class, and Danny was homecoming king. Of course, they were home-schooled...but their Mom showed no favoritism. She brought up them boys the best she could after their father ran off to Corpus with that whore. She is also a card-carrying member of the KISS Army among other paramilitary militias.
Extra deduction for the Single White Female 2 (Redneck Boogaloo) vibe.
And for keeping that girl in the trunk in the crawlspace. Let her go, guys.
What this tattoo says about the wearer(s):
