Repetitive text bombardment 

To send more than one message to a person before they have a chance to reply, making the sender seem needy. The sender often doesn't understand that the receiver probably cant reply because they cant get to their phone at the moment, so repetitive messaging is pointless.

When I switched on my phone I had five messages from Sam. Serious repetitive text bombardment.
