2.
A self-forced vomit when one forcefully purges himself after drinking heavily so that he will be able to have sexual intercourse with his bootycall/any girl and avoid vomiting all over her in the middle of intercourse.
Alex: Bro, Katie just texted me to come over.. but I'm so fucked up I think I will be too nauseated to fuck her.. I might puke all over her...

Josh: Dude, just have a tactical vomit and go tear that pussy apart!
