1. Bob knows over 12 languages, and I've never heard him speak any other language apart from English. What a language slut.

2. Faye is such a language slut. She starts all these languages, but gets bored with them after only a few days.

Get the Language Slut mug.
slut language is the way 2 or more sluts communicate using words/ phrases no one other than sluts would understand.
Emily and Brooke were definitely talking in slut language last night.
