When receiving oral felatio or a "blowjob", you purposely fail to warn your parter when you are about to ejaculate or unload, apon climaxing you pull out her lower lip and shoot carefully so in the end it will apear she has a huge lipfull of chewing tobacco or dip.
dude 1: so did you talk to your girl lately?
dude 2: nahh she's still pissed as fuck about the louisiana dipcan I gave her the other night.
dude 1: oh haha!!
