Sluzie (noun) A girl who is rather silly, and probably slutty--or at least you'd like her to be if you'remale--and is homely enough to pass as a "plain Jane" or "Susie Q" in appearance or personality.
The ability girls and women have developed to hold several items at once in one hand. The skill has been developed due to the lack of pockets in women's clothing.
I thought she'd need multiple trips to carry her phone, keys, wallet, and Starbucks to her car since she needed the other hand to open the door, but she used her impressive girl grip to carry everything in one hand.
