some lady

some girl

some actor

"Some" is only used this way in casual spoken English.

a creepy (person)

A "creepy" person is someone who makes you feel uncomfortable. They might do things like:

• staring at you a lot
• standing too close when they talk to you
• calling you too often

This kind of "creepy" behavior makes you feel like this person is strange and unsafe. It might make you think that the person is going to stalk you or attack you.

People who ask you out on dates can be "creepy", but it's also possible for your coworkers, boss, or uncle to be "creepy" as well. It's a lot more common for men to be called "creepy" than women.

(someone) hit on (someone)

"Hitting on" someone means trying to create a sexual or romantic situation with them. Here are some ways to "hit on" someone:

• asking them out on a date
• asking for their phone number or email address
• complimenting their appearance

You can't really "hit on" someone who you're already in a relationship with. People usually "hit on" people who they've just recently met.

The phrase "hit on" doesn't sound especially negative. You can say that someone "hit on" you, whether you liked it or disliked it.
