A celebrated time for potheads all around the USA (and possibly other countries) because it is believed that at 4:20, whether it be night or day, one should partake in the activity of smoking marijuana. It has practically made its self a holiday if you look at the date April 20th, which in months and days would be, in fact, Four Twenty.
Rejoice little potheads, for this might just someday be put on a calender expressly for the use of the 99 Cents store.
Bud: What time is it Mary-Jane?
Mary-Jane: *inhales* It's four twenty.
