Sidebro

A bro who is not really part of your main group of bros, but is chill enough with some of your bros that he can occasionally hang out with your main group of bros.

Hey guys, lets hang out tonight. You can invite any of the sidebros if you want.

sideboob

A view of the female breast seen from a side; generally under loosely-fitting clothes. Very titillating (pun intended) and sexual without showing any overt nudity.

There is so much sideboob at Los Angeles awards shows!

My brother's g/f's sideboob totally distracted me from my own g/f.
