In the plumbing field a nipple is a predetermined short length of pipe usually NPT(National Pipe Thread). A NPT threaded nipple can be made of almost any material and can be in sizes ranging from 1/16" to 24" NPS(Nominal Pipe Size). The plumbing nipple gets it's nickname because of it's similar function to that of a female nipple in humans and animals. It's usually a small protrusion which emanates fluid or gas.

"You want your nipple an 1 5/8" off of the finish wall in this situation."

Nipple 

The beach is one of the few places there would be any actual double standard that works in a males favor, since males do tend to walk around with no shirts on at the beach, and females don't. It would also be one of the few double standards that does not work in a female's favor in life. Though if every female that went to the beach really wanted to walk around topless did so, there would be a lot of females to arrest hypothetically, since you don't often see any females arrested for walking around topless, or for exposure. The real question is would females want guys staring at their tits all day, which would be inevitable, and is the social conditioning that females go by when keeping their tops on. Nobody is staring at a male's nipples at the beach.

Females have to look and try hard to find a double standard that doesn't work in their favor, males know they're working hard on it since its males who are fucked over the most in life. Males aren't going around everywhere showing a nipple or two though, the beach or the water, a lake are some of the few spots males aren't going to get locked up or kicked out for having no shirt on.
