You're really asking an open-ended question. If it was a greeting kiss, then it's nothing more than a social gesture. If no one is coming or going (no puns intended), then I would think it's probably something more. FYI, though: A bisexual person operates the same as a straight person or a gay person. The only changes are their orientation. They don't necessarily have an entirely different way of acting like you seem to think they do. You'll have to be more descriptive in your question.
I miss your mouth and your chocolate kisses
A beso en la boca means to french kiss or to literally kiss in the mouth. Beso means kiss en means in la means th boca means mouth in the spanish language.
it means Close your mouth. AKA stop talking.
To keep the mouth and mouth close (kiss), I think.
It probably means he's not that into you or either his/your breath stinks.
it could mean "kisses". like when someone writes "oxox", that means "hugs and kisses". so the "xx" could mean just kisses. -------------- It means 2 hugs. X means hugs (crossed arms) and O means kisses (round lips/mouth/pucker).
"La bouche" is the mouth in French; "besos" doesn't exist in French, but is the Spanish word for "kisses".
kisses on messages
* You must be sure this girl is bisexual and not listen to gossip. Bisexual women can be just friends without sexuality entering the picture, but, if you feel she is getting too close to comfort then let her know you are not bisexual and never will be. Honesty is the best policy.
"close your mouth you bitch"
LOLXX Would probarly mean Laugh Out Loud and two kisses
what it butterfly kisses
