In fact the verb 'bebetear' is for colloquial use and outside the English dictionary, and one of the drawbacks to defining it is that its use and origin depend on the context. 1o_ It is a drinking deformation, usually in a festive environment. What that termination does is reinforce the action, so that it is interpreted as "drinking (alcohol) excessively or with great pleasure". 2o_ Taking as a reference to baby, it can be "behaving immaturely", "simulating a childish attitude (here is related to bebotear) " or "seeking as a loving and/or sexual conquest a very young couple".
