tongue biter 

bad French kisser who will bite, scratch, or harm the other person’s tongue in some ridiculous way during the kiss

Jen and I were making out last night and it got too crazy and she cut my tongue or something. She's a real tongue biter.

Tongue biter 

A person, usually a female, under the age of 18, only posting selfies on social media. These selfies mostly include Snapchat filters, lighting, tongue biting, etc. Conclusion: They’re just children with high egos.

Did you see Kenzie’s new post? She’s such a tongue biter.
