【Idle】 ,  【loaf】 ,  【lounge】 ,  【loll】 ,  【laze】  mean to spend time not in work but in idleness.

【Idle】 may be used with reference to persons or to things that move lazily or without purpose; it may also be employed to connote either strong censure or a pleasant or justifiable action.

【Loaf】  suggests either a resting or a wandering about as though there were nothing to do; it does not necessarily imply contempt, although its agent noun loafer when used seriously nearly always carries that implication and has often affected the meaning of the verb.

【Lounge】 , though occasionally used as equal to  【idle】  or to  【loaf】 , typically conveys an additional implication of lazily resting or reclining against a support or of physical comfort and ease in relaxation.

The agent noun lounger is, however, usually derogatory, though slightly less so than loafer.

【Loll】  also carries an implication of a posture similar to that of  【lounge】 , but it places greater stress upon an indolent or relaxed attitude.

【Laze】 usually implies the relaxation of a busy person enjoying a vacation or his moments of leisure.
