A deceptive software demonstration downplaying the slowness or difficulty of actual operation with phrases like "isn't this great?" "You can do this!" "Almost realtime rendering!"
The seller uses oleaginous phrases and a kidstuff demonstration, leading the victim to falsely believe that the same stupendous calculation speed occurs with an elaborate detailed model of a hospital or the complex spreadsheet of an international corporation.
"Dang! They got me believing that my hotel project would render as fast as their little 3D house model. What a lie! I'm a fool! It was an Introsuction!"

The very beginning of a blowjob where someone sucks the tip of the dick before giving a full blowjob. It's the prep work that leads into the full blowjob. This period of time varies greatly in length depending on the resistance of the receiver and the skill of the giver.
Person 1: Dude, that new girl in our class gives a really good introsuction! It was perfect - long and teasing. The rest of the blowjob was eh.
Person 2: Man, at least you get a blowjob...
