A term used to describe a
party or activity where guests are encouraged to arrive under the influence of LSD. A
tab of LSD will often cost around ten dollars, hence the name.
When it is a requirement, security will sometimes
check guests' tongues before allowing them in and charge a cover if they do not see a tab.
Guest: "Yo,
man, whats the details for Saturday?"
Host: "BYOB, girls
get free drinks, BP, no
cover, ten dollar admission, starts at 8"
