Get the Fap, Crap & Nap mug.
Fap crap and nap comprises the three most important facets to a daily regimen. Masturbation, defecation and siesta. It should be performed in that order for maximum efficacy. It is often utilised by university students as a means to maximise brainpower where required.
Student 1: Mate class sucks today, I don't know how much longer I can endure it.
