it could mean many things or it could've just trembled but usually a kiss
It means you like the person.
yes guys do like lips (from women not from men)
no, means you guys both kissed the same dog.
It could mean that he is attracted to you and is imagining kissing you, or it could simply be a habit he has while talking. Pay attention to other body language cues to better understand his intentions.
Umm, that they totally like you and want to make out with you?
some guys
sometimes we bite our lips because we are nurvous about something or it becomes a bad habbit so if you see a boy biting there lip and there staring at you that could mean he likes you
no no no

"los labios" mean lips
"Tamblón" translates to "log" in English.
If the boy looks at your lips and then into your eyes when you guys are talking then yes he wants a kiss ! (;
