A phrase to show one's affection to another. 10th grade science class where i come from is CHEMISTRY. If the person that you tell this phrase to asks WHY? Just say "cause there's sooo much chemistry."

Friend 2: "Why?"
Friend 1: "Cause there's sooo much chemistry!"

A far-below-average dude who is usually passed over in favor of more "succulent 'n' satisfying" male-meat by all but the most ugly/desperate/undesirable hussies who would otherwise have little chance of getting laid.
Economy-grade studs may not necessarily be dislikable guys per se, but they tend to be sorely lacking in the "hot 'n' heavy" department --- they may have low stamina in bed and/or perspire excessively during intercourse, only cum a weak dribble and/or have to wait several days to "recharge", have a small/narrow wee-wee, be very overweight and/or older than dirt, have an apathetic/lackluster personality, etc. Extra points if they are financially-solvent, though --- at least they won't mooch off the lady they're with at the moment, plus they may even be willing to assist HER with the cost of a few groceries and/or housewares.

A condition where a student's grades are lower than expected. It is the opposite of a grade surplus where you get a higher than expected grade.
John just got the results from his exam he was so confident but now he calculates he had a large grade deficit
