A sexual position or maneuver in which a male inserts a glass or Pyrex-based test tube into the anus of his partner and then proceeds to masturbate into the test tube, filling it with semen. He then executes a well placed donkey punch, causing the partner's sphincter to contract, effectively breaking the test tube, thus bursting into an explosion of blood, shit, semen, and glass shards.

Get the Mad Scientistmug. The act of defecating on your partners head whilst they are sleeping. Upon waking, the person will notice the steaming turd and immediately become mad - hence the term "Mad Hatter"
Sharlene really annoyed me by not giving me head last night, so I dropped a Mad Hatter on her! Looks like I wont get head tonight either !
