look up any word, like sex:
A person who gets turned on with an intelligent conversation with others. This happens usually while speaking to the opposite sex, unless of course if they are homosexuals. These intelligent conversations can lead to higher levels of attraction among the two in most cases. If you are a male 'IQ sucker' and find that the girl you are talking to can hold an interesting intelligent conversation with you, she automatically becomes a lot hotter, and vice versa.

An IQ suckers tend to feed on information and are well informed about varied topics under the sun.
Priya - Intelligent conversations are such a turn on!

Roan - Totally! We are such IQ suckers I tell ya.
