Lol

Internet slang. Short form of 'laughing out loud', but often mistaken for 'lots of love'.

Mom: Welcome to the funeral of our beloved aunt Tammy. LOL!
Son: ..why did you just say 'LOL', mom?.
Mom: Uhm. I thought it meant 'lots of love'? ..

rejuvenated

If you feel rejuvenated, you feel younger than you actually are. Sad part, it's all in your head and might turn out to be embarrassing for others.

Mom: Let's go party tonight! I had this massage and feel so rejuvenated. C'mon, we could both check out some guys!
Daughter: You're embarrassing..
