“Mostly publishes in specialist journals” (i.e. his papers are not good enough for a top journal) and “papers are mostly descriptive” (i.e. her work is boring) are just two of the phrases scientists use to insult their peers, as collected by stem cell scientist Paul Knoepfler on his blog. Other insults include “mostly middle author publications” (i.e. he is a loser) and “outstanding educator” (i.e. her research output is negligible).
