In many cardrooms, with respect to an all-in bet, only a full (or half) bet can be reraised. Anything less than a full (or half) bet is considered to be action only, that is, other players can call the bet but not raise it. For example, Alice bets $100. Bob calls. Carol goes all in for $119. When the action returns to Alice and Bob, they may only call the extra $19; they cannot raise it. Carol's raise is called action only. Compare to "full bet rule", "half bet rule".
