This can be done while taking a very massive shit and having a excess amount of mucus in your mouth.
1. look down
2. aim between the tip of your shaft and the front part of the toilet seat, no homo.
3. let that baby fall.
If successful you are a skill spitter, if not, your just gay.
oh man that huge shit was so good i just had to test my spit skills, and attempt the Skill Spit.
