Johnny Manziel and Kenzie Werner are clearly getting serious ... the two have now reached the stage of getting in makeout sessions while on hot arcade dates.
The new couple(???) hit up Dave & Buster's for a fun night out on Tuesday -- and in between air hockey and shooter games, the two cozied up in the place's photo booth.
In pics that Kenzie shared to her social media page, you can see Johnny and the model got REAL close for the camera -- kissing and hugging in each shot.
