Hot dogs and other long Frankfurts/sausages (including cheese dogs), footlong sandwiches (like those from Subway), eggplants, Popsicles, butternut squash, bananas, and/or any other food shaped of this sort. Guys love to post pictures of these foods online before they eat them because:
*Theoretically: It gives girls more attention (yes, that even includes their mom as well, even though she already has a husband)
*In reality: They are attention manwhores who have no friends at all to hang out with after school/work.

Girl screenshots to send the pic to her BFF
