fossicking (around): used in mining to heap mighty scorn on an individual or group what undermines another's digging, or the act of searching for "waste gold" in the mine's rubbish; outside of mining, it relates more broadly to any attempt to find an object etc. by which one might gain.

interrobang: a combination exclamation point and question mark, for those occasions when either one alone is just insufficient.
scabrous: scandalous and risqué, or rough surfaced (covered in tiny projections)
