snivel gear
n.— «As for a modern day joe, this is what I carry; couple pairs of socks, T-shirts, MRE’s, shaving kit, slepping bag, “snivel” gear (poly- pro), GPS, NVG’s, ponchos, and radio w/ extra batteries. Also have a polypad for laying on the ground. Almost forgot the most important thing! My WOOBIE!! You might call it poncho liner. It’s a lifesaver on those cold nights in the patrol base.» —“Re: What’s in the pack?” by SJSNYDR Usenet: alt.toys.gi-joe Sept. 26, 1998. (source: Double-Tongued Dictionary)
