It's a sort of Japanese archetype for female characters/love interests... "tsun" refers to someone who, by outer appearance, is rough, insulting, kind of a jerk, and most of all defiant of her feelings towards someone else, and "dere" is someone who is sweet, sensitive, and quite open about her feelings. You can either have a typical tsundere have the "tsun" side be dominant or the "dere" side be dominant. One is usually something of a cloak for the other.
