Monsters Theory
Monsters Theory is the now-mainstream belief that very large breasts on young, lean women is the single most attractive look a woman can have, despite it having a relatively limited genetic basis (as studies of female siblings have shown) There is no established explanation for how women with 25-30% body fat and large breasts have their figures but luck seems to play the biggest role, since their looks and their breasts both are not an accurate reflection of their parents. The theory that attractive parents produce attractive children has become eroded due to monsters theory. Monsters theory states that genetics play some role, but far less than expected and otherwise ugly, fat parents with not particularly good genes can unleash bombshells on the world.
The Urban Dictionary Mug
Purchased this mug as a Christmas gift. Can’t wait to see the reaction!
This is to test if the Urban Dictionary store rating system is working and not showing fake 5 star reviews.
These are hilarious! Great gifts. Cost seems a bit high but i couldn’t resist.

It’s a great way to store my pencils.
