\framed puts the content in a \hbox and when you put a \hbox in a math
environment the text in the box is typeset in text mode, this feature is used
for the \text command. To get now the content of the \StrikeMe command in math
mode a different definition.
\defineframed[StrikeMeFrame][background=strikeme,frame=off,offset=0pt,location=low,backgroundcolor=blue]
\define[1]\StrikeMe
{\ifmmode
\StrikeMeFrame{$#1$}%
\else
\StrikeMeFrame{#1}%
\fi}
