From www.urbandictionary.com "Sucker love" and "Suckers dream" are lines from the song "Every me and every you" by Placebo. Sucker love means using people for sex until you get bored with them. It's the complete opposite of relationships and love. "sucker love I always find, someone to bruise and leave behind" "Sucker's dream" means that the young person was tricked/sucked into believing that they were in love "Just 19 this sucker's dream I guess I thought you had the flavour"

If you gives us some context would be great !!!!! ...but I think "sucker love" is a person who always get hurt because he or she 'falls in love"really easily. (aaghhh judgments! ... I don't like them ^^) =)
