A social gathering that involves many females. There are only a few males present at a clam fest, thus making them more appealing to the abundance of females.
The act of forgiving the woman you just had sex with for having a nasty-looking vagina. This is sometimes viewed as a face-saving act for those who are having post-impulse sex guilt, but were too horny to care prior to the intercourse.
You have an exam, right, and instead of studying for it over a long period of time....you sqeeze it all into one night, generally the night before the exam..these exams also tend to be major exams, i.e. the junior and leaving cert exams...or college end of year exams!

Grainne: Cramfest it is then!!!
