(n.) grundlecakes are created when excess vaginal secretions seep from the vagina and run down to the grundle where they dry forming a flaky, crusty, build up. This usually occurs during aggressive foreplay or hardcore sex in the missionary position when the female becomes increasingly aroused and wet. The term grundlecakes refers to both the caking of the vaginal secretions to the grundle area, in addition to the actual flakes and clumps that shed from the grundle upon the bedsheets. Grundlecakes is not merely a female phenomena but can form on the male if the vaginal secretions are spread during intercourse to his grundle and dry there.
Erin was slightly disgusted and surprised to find grundlecakes all over her bedsheets the next morning after Anthony provided her with a weeks worth of orgasms the previous night.

While having rough sex the male tangles and tousles the woman's hair into a nest of sorts. When he is about to finish he pulls out and busts into her hair to give it the finished product hold, resembling a birds nest.
After Erin complained she ran out of hair gel Anthony fucked her and finished in her hair leaving her with a birds nest.
