If a parcel has been delivered to you via clenched bumcheeks, it is said to have been delivered in a 'bumvelope'.
My sandwidge arrived in a bumvelope.

The concept of bumveloping, i.e., 'to bumvelop', originated from a discussion of the pentration vs envelopment argument. Bumvelopment is defined as an act of envelopment specifically utilising the anus as a means. Key to the understanding of bumvelopment is that it is in fact an act of dominance in the same sense that penetration has traditionally been seen as dominant.
