I start to go running with a friend a few weeks ago and we pick up this new habit, when we have finish our jogging we go buy a bag of chips each (of course). So fritting is a mix between frite (=chips) and jogging.
Here the translation just follow the direction to see who is talking :
"That's it we run 10 minutes."
"We walk a little bit!"
"Then chips.(bread, Pringles)"
"We deserve it."
