Sweating at the seams

In this YouTube video, commentator Adam Mockler is describing a Republican congressman who went on ABC’s This Week with George Stephanopolous. Mockler describes the guy as nervous, and “sweating at the seams”. The malaphor appears around 38 seconds into the video:

This is a conflation of “sweating like a pig” (sweat profusely) and “bursting at the seams” (very full to overflowing). If perspiration appeared on his jacket or shirt, perhaps this isn’t a malaphor after all. A big thank you once again to Mike Kovacs for spotting this one and sending it in.
