1. To tantalize or torment one with something they cannot or should not have. I'm trying to stick to my diet, but my roommate keeps teasing me with all the cakes and cookies she likes to bake. I loved teasing my friends with pictures of sunny beaches while I was on vacation in the Bahamas.

2. To arouse one sexually with something, especially with no intention of engaging in sexual activity with one. I've just never understood the appeal of strip clubs. You pay to go watch women tease you with their naked bodies and erotic dances, and then you just leave more sexually frustrated than when you arrived. She kept lifting up her skirt to tease me with glimpses of her thighs.
