HTD

Hug
Transmitted
Disease

Similar to an STD, except made up, it is the excuse teachers give for why you can't hug in skool.

Guy 1: K, well I guess I'll see you in PE.
Girl 1: Ok bye.
*girl 1 hugs guy one*
Teacher 1: No hugging in school! Do you want to get Arm Herrpies??? It's the most common HTD.
*Teacher 1 and girl 1 walk away in opposite directions*
*guy 2 walks up*
guy 2: wow, Mrs. Teacher 1 is evil.
guy 1: I know there isn't even such thing.
