A relatively short amount of time that feels dramatically longer than it actually is. This term is derived from the common psychedelic tryptamine alkaloids (e.g. psilocybin etc.) and the sensation of anomalous temporal distortion they often provide.
George experienced a tryptaminute when he was on magic mushrooms. He felt as though at least fifteen minutes had gone by before the display on his digital clock changed at all.
