A lewd sex act between a male and their partner (male or female), in which the partner takes a small, semi-spherical and semi-rigid poop onto the head of the male's penis. The partner then uses one or two fingers to push down on the tip of said penis super fast, being sure to pull their hand away in hopes that the slingshot-like upward bounceback of the penis will fling the feces into his mouth.
(Successful dismount of doo-doo depends on practice; length, rigidity, and elasticity of penis; and the consistency, size, and moistness of feces.)
Whilst receiving a blow job, on the verge of ejaculation pull back on your woman's head with one hand and press down on your johnson with the other. After lining up her chin with the projected path of recoil.. release. The spring-loaded wang will then rocket upward pounding the chin of the unsuspecting female resulting in a explosive orgasm, drenching her neck and chest with cum in a splash-like manner; Not unlike a divingboard.
EX 1
Phil: "I can't get Heather to shut up. How do you deal with Amanda?"
Steve: "In desperate times I just give her The Dutch Divingboard. That'll shut her up."
EX 2
Heather: "Why are you talking so funny?"
Amanda: "That jackass, Steve, gave me a dutch divingboard earlier and I bit the shit out of my tongue."
The word often used to refer to the monstrously huge metal bumpers found on the BMW E30 3-series from 84-87. The e30s of the year 1988 also came with d-boards however they were slightly shorter and the plastic bumpers from the 89+ e30s fit without any modification.
If you have an older e30 the plastic bumper swap is not so easy and requires some alteration to fit but nonetheless can look stunning.
D-boards can also be tucked and/or painted. The tucking method involves the owner drilling the bumper shocks and compressing them to make the bumper shorter. Painting the d-boards is also a nice touch and prevents them from making small children cry during the daytime.
