cleavage is the tendancy of a rock to break on an flat surface.
her cleavage was hanging out of the V-cut shirt.
Manga was very popular because it was very different from other books. Instead of words, there were drawings instead. Many kids and teens loved this, but the adults didn't like it very much. (No adult I know thinks manga is cool.)
I think a girl needs to try her best to look pretty and when a hot guy flirts with you flirt back and this is not a nessecity (depending on the type of guy) show of some clevege sometimes I think if a hot guy flirts with you then you should flirt back and this is not a nessecity (depending on the type of guy) show off some clevage sometimes.
