What do you say to some phrase and words related to romance?
Okay, I hear you. Let's go.

If you check someone out, it means you look at someone because you find them attractive or interesting.
ex: There was a girl at the party sitting alone, I couldn't help checking her out.

player - this word is usually used for boys, sorry guys, a player is a boy who likes to chat up girls.
ex: He was a rich guy and a little bit of a player.

go on a date - to meet someone who you are romantically interested in. You can hear that idiom a lot in movies.
ex: I started using Tinder and going on lots of dates.

single - if you are single, you don't have a boyfriend or girlfriend. Sorry.
ex: If she's single, I am going to ask her out tonight.

chemistry - if there is a chemistry between two people, they like each other and are interested in each other
ex: It was obvious that there was a real chemistry between me and Hermiona.

to flirt - if you flirt with someone, you talk to them in a way that shows you are attracted to them and maybe want to have a relationship.
ex: I don't like flirting with girls but :))

There you go, you learned something new today, good. Advice from me, if you like someone, go talk to them. If they're not interested, leave it there. Now, close your eyes and listen to this song.
