Beck In Bikini Bottom
Let's be honest here, even in Bikini Bottom, most of the teenage girls there are also attracted to him and have a crush on him, making the other teenage boys jealous of him and see him as a threat even though he's actually a laid back, soft spoken, nice guy who wouldn't hurt a fly and gets along with mostly everyone, which is one of the reasons why the girls fawn over him and not just his good looks.
He did once get in trouble with one of the teenage boys in Bikini Bottom because the guy, who was a jock at a high school, had a girlfriend who was flirting him. The guy thought Beck was stealing his girlfriend and wanted to fight him about it but Beck had told him that he wasn't trying to steal her away and that she was flirting with him but the guy wasn't buying it. Jade, using her reputation as the "scariest human in Bikini Bottom", had stepped in, scaring the guy away by threatening him and telling him to leave her boyfriend alone.
Girls only flirt with him whenever Jade isn't present because they know how scary Jade is and they definitely didn't wanna wanna deal with her or know what she would do to them.
One time Mr. Krabs had tried to use him for his popularity to make more money by having him "sit there and look pretty" while sitting at his restaurant since mostly everyone found him to be really nice to look at and not just teenage girls. They even like to touch his hair because they found it to be absolutely perfect and so soft.
Beck is one of the few of Tori and Cat's friends that Squidward actually likes and tolerates since Beck is really chill and not constantly bothering him or invading his space.
Some had said that he has a face carved by angels and his hair was so perfect that it could compete with a mermaid's. He is considered the most beautiful looking human guy they've ever seen.
