A laxative. Commonly used as pranks to make the person have to use the bathroom frequently. Over dosage can cause rectal bleeding. Can come in a chocolate form (like hersheys).
God he should be bleeding outta his ass because of all the ex-lax you gave him.

The security protocol no longer used at LAX airport for cavity searches, now replaced by body scans.
The last time I left LAX I got the full monty, personal body/cavity search. It was great. Sadly, that's passé, replaced now by body scans. They said the old security was too lax. No more personalized cavity searches, they're all Ex-LAX now.
