I really, really wish we could degender “guy” and “guys”. I know plenty of people of all genders that use the words in general to describe people, objects, concepts, everything. The only holdouts are people that insist on it specifically meaning males. Ironically, these people are often the hardcore feminists.
If other English words can change their meanings and be claimed/reclaimed by certain groups, why can’t others?
Take guy! Use it to describe whatever you want! Free it of its historically phallic shackles!
