Although "boys and girls" is the most common lemma, "guys" is a pretty common synonym, especially when you're used to referring to only children as "boys". Might be a regonal thing. My intuition is usually to type 1guy first, because I'm not used to uploading guys/boys. This might also help new contributors discover the 1boy+ tags if they try typing 1guy first.

5guys could be mistaken for five guys burgers and fries if you're retarded.
