when you cant quite finish what you are doing or saying, due to an express of air
1)whilst in the middle of a funny joke a burp takes you off course.
2)whilst in serious conversation you cough and end up spitting in the face of your mate.
3)whilst in mid-excreetion, a pocket of air channels out your backside causing splutter on the rim
An intense jerkin' session which ends in extreme self pleasure.
Tugging you'r meat fast, which then ends in splutterness all over ur hand....and maybe you'r face.
avoid eye contact
