Cultures differ, but in most countries spiting in general and especially spiting in someones direction would be seen as insulting. So the answer is probably NO.
Hygienically, spiting is not to be encouraged, it is a needless action and is likely to spread germs.
well he could like you, but judt bcuz he waved to u doesnt mean he likes u
If a guy shows off that means he either likes you or he just wants attention from everybody.
it doesnt mean he likes you.
yes
It sometimes means that he likes you, but not always.
That means that he probably likes you.
It means he likes but has a girlfriend.
That he likes you?
It just means she thinks the guy is ugly. It means that the girl likes the guy...I'm a girl so that is what i would do sometimes to get attention from the guy i like.
he likes you
If a girl takes her shirt off in front of an guy then its a high chance she likes the guy
If a guy says that you are pretty it does not mean that he likes you. He could like you, or he could just be paying you a compliment.
