Noun, Someone whose happy romantic relationship absorbs all the available love in their surroundings, leaving their single friends and colleagues unable to find happy romantic relationships of their own. Can be used to refer to long-term, committed relationships or to couples in the beginning stages of a relationship. Can also be used as a verb, i.e. "to love-suck"
Oh, you two are so cute. You're such love-suckers!

We can't be friends anymore! I can't ever get a boyfriend because you're such a love-sucker!

I don't mean to love-suck, but we're just so happy together.

Get the Chump Love Sucker mug.
from a song "evry me and every you" by Placebo, "sucker love" is using people for sex until you get bored with them. It's the complete opposite of relationships and love.
