There are several signs of a chintzy person, they are:
a) When playing against them in a game of tag, they will often say "not playing" when they know they will be tagged.
b) After watching you get to the last level of an original Nintendo game, they will push in and hold the power button, threatening to let it go.
c)If ever giving a guy head, they will direct the load at his face instead of swallowing.
d)When everyone is munching out, they will hide their goodies while they eat yours.
e)A person who makes their partner wait for marriage to have sex.
f)A chintzy guy will tell all the hot girls that his friends are gay to improve his chances. And if he is really chintzy he will pretend to be gay just to make other gay guys chances less successful.
g)A chintzy girl will strategically never have any girlfriends just to improve her chances with guys. Note that this girl will say that she is on birth control when she is in fact not.
i)A slightly less chintzy girl will only hang out with girls far less attractive than herself.
