I know that third reactions are extremely uncommon but what would be example of a real life third order reaction?

The hydrolysis of sucrose in acid solution is third-order, r = k[sucrose][H+][H2O]; however, the concentrations of both the catalyst H+ and the solvent H2O are normally constant, so that the reaction is pseudo–first-order.

The rate constant for a third order reaction would also be M-2 s-1 if time was given in seconds.

also if you had a reaction with A+B+C -> products

that could be a third order reaction.

What would be the integrated rate law for a third order reaction?

The general example of a third order reaction is one where 3 molecules must collide, making it unlikely to occur as this is an unlikely event.
