Courtesy of Bruddah Superman67, for people who wanna increase their chances of getting french kisses from the WLs:
Friendly - Must put on a friendly front inorder to built chemistry
RTF - RTF her will have more chance to built some KC & have better chance to french.
Engagement - Engage in nice & interesting conversation, sweet talk, exhibit TLC, be a real gentlemen, buy gift if you have deep pockets, etc.
Neat - Present yourself in nice & neat attire as 1st impression is of paramount importance. Comb your hair neatly, apply parfume and clean shaven but not on your down south area as PRC WLs prefer some hair over there.
Chemistry - If you click with her, chances of frenching is pretty high.
Hygienic - Must have good oral & personal hygiene to enhance your chance of getting a french kiss, bad breath or awful looking teeth is a confirm No No!
