slang A credit card. You need some distance from your flexible friend if you want to get out of debt.

slang One who identifies as mostly, but not completely, heterosexual. Because "hetero" here indicates one's primary sexual orientation, the term is seen by some as a more specific alternative to "bisexual" and by others as a label that discounts or erases bisexuality. I usually think of myself as heteroflexible because, even though I'm a woman who's only dated men, I don't think I'm 100% straight either.
