m&m's

A chocolate candy the melts not only in your mouth, but in your hands too.

I just took a handful of M&M's and now my hands are all sticky. How exciting!

MSM

1.) Mainstream Media; the broadcast (films, television, radio) and print (newspapers, magazines) media produced by one of the large media conglomerates (in 2017 five corporations controlled 90% of US media. Source: wikipedia). Is often used pejoratively due to concern that it lacks a diversity of viewpoints and can unduly influence Americans' understanding of and opinions about events. MSM is juxtaposed to alternative, or independent, media.

2.) Men who have sex with men. Commonly used in healthcare and public health because it is more concrete and useful in medical decision-making and epidemiological data collection than the ill-defined social contructs gay/homosexual/bisexual/'identify as straight but sometimes have sex with men'/'gay but celebate'/etc.

1.) The story was first reported on a popular blog, but was soon picked up by MSM.
2.) MSM should be tested regularly for syphillis as the disease is more common in this population.
