The giving or receiving of a large hit of meth from a long "V" shaped tube. The "giver" starts by taking a big hit which he in turn blows through the tube all the while keeping the fire on the meth and blowing more meth into the "receivers" waiting mouth, until they can take no more. May cause you to drop to a knee. Keep in mind that should one fall after receiving a Blow Job, the five second rule does apply. After numerous hits from the Blow Job tube it then becomes a Jo Blob
I stopped by for a Blow Job before work and will have no problem working my double shift now.
