Bicycle Shorts 

When a male gets a boner and his shorts become tight, it appears as if he is wearing a pair of bicycle shorts.

When Jerry saw Linda walk by he was wearing bicycle shorts.

Bicycle Day 

Bicycle Day is April 19, commemorating April 19, 1943, when Dr. Albert Hofmann first took LSD intentionally. Three days earlier, he had absorbed a small amount of the drug either through his fingertips or by accidentally ingesting it. On Bicycle Day, he took 250 µg of LSD intentionally and, fearing he had made himself ill, cycled home from his lab. During his bicycle ride, he experienced the effects of LSD, making this the date of the first ever acid trip. He wrote about his experiments and experience on April 22, which was later put into his book LSD: My Problem Child.
This day (for LSD users) is when they celebrate the discovery and first ever use of the drug
acid LSD trip

joe spent bicycle day at home with 250 grams of LSD, just as the amazing albert hofmann had done in 1943
