From the source of jungle/dnb lingo, the Junglist Dictionary: Bo! - Simulated gunshot. When a tune is big, say this loud if you want a rewind. In Jamaica, people used to fire blanks all the time when a tune was big. For a definition of rewind, see the Junglist Dictionary you lazy bastards.
Gymnosperms are a type of plant that reproduce by a seed that is not enclosed as with angiosperms who have seeds contained flowers. Many of these plants are conifers or cone bearing plants. Gymnosperms are found throughout the world. They have roots and stems. Their leaves are in the form of needles in conifers.
The evolution of the gymnosperms brought an entirely new concept to plant reproduction: seeds. Unlike the ferns and bryophytes before them, gymnosperms had no need for extremely moist conditions for reproduction. Instead, embryonic plants were neatly packages for dispersal and germination in favorable conditions. In other words, gymnosperms rocked the plant world.
