I'm a Mexican American and don't know much about the culture. A friend that's a young lady was a bit down and I told her I had a hard time at work but I would talk to her soon and I said love you dude. To be nice she said it once when she was drunk and you know I used te quiero because it's a more platonic use of the word ik she isn't into me her messages are too lacking for it to be flirtatious. anyway I said ttyl love you dude and she said love you silly billy talk soon ik being called silly billy. I mentioned she reminded me of this show I watched a character on there that's his catchphrase and she said oh okay well you are a silly billy. If anyone knows what it's comparable to in American culture or better yet Mexican culture it would be appreciated. I want to know if I sould jab back or give a little nick name back but silly billy has no meaning to me.
