When meeting a person online or in a video game posing as a female to get money or items, and later turns out to be a man.
John: Man, I met this girl on WoW the other night. We sexted for hours.
Rick: You mean Superhotty6969? Yeah, pretty sure that's a dude.
John: No way, I think my junk would know if it was a dude.
Rick: Sounds like erection deception to me.
When ur dick bulge is big but when u whip it out it's small
My girl thought my dick was huge but then realized its was a Deception Erection.
